Black Beauty Stick Insect (Peruphasma schultei) Care Sheet
The Black Beauty Stick Insect (Peruphasma schultei) is one of the most distinctive phasmids maintained in captivity. Its velvety black body, contrasting pale yellow eyes and vivid red hindwings give it an appearance unlike the more conventional brown and green stick insects.
The species originates from northern Peru and was scientifically described in 2005. Despite its exotic appearance, Peruphasma schultei is generally considered relatively straightforward to maintain when its requirements are understood. The Phasmid Study Group lists it as an easy species in culture and records privet as its principal captive food plant.
However, there is one particularly important difference between this species and many other commonly kept phasmids:
Black Beauty Stick Insects possess a chemical defence.
When threatened they can release a defensive secretion from glands behind the head. This secretion can irritate sensitive tissues, particularly the eyes, so unnecessary handling and deliberate provocation should be avoided.
Successful husbandry centres around excellent ventilation, moderate humidity rather than constantly wet conditions, room-temperature warmth, fresh pesticide-free privet or another proven food plant, adequate moulting space and sensible handling precautions.

Natural Distribution
Peruphasma schultei originates from:
Peru.
Captive stock is associated with the Cordillera del Cóndor region of northern Peru.
Reports from experienced breeders place the species at approximately 1,200–1,800 metres elevation in its native region.
This is useful husbandry context because Black Beauty Stick Insects should not automatically be treated like animals requiring extremely hot, saturated tropical conditions.
They generally perform well at moderate room temperatures with good ventilation.
Natural Food Plant
In its native environment, Peruphasma schultei is associated with plants of the genus Schinus, including the Peruvian pepper tree.
Research concerning phasmid feeding biology identifies Schinus molle as a natural food plant for Peruphasma.
Fortunately, captive animals readily accept much more accessible plants.
The most important of these is:
privet.
Appearance
Black Beauty Stick Insects have a very different appearance from traditional twig-mimicking phasmids.
Adults possess:
- A velvety black body
- Pale yellow or yellowish eyes
- Contrasting red mouthparts
- Small red hindwings
- Relatively short, robust proportions
- Long antennae
The combination of black, yellow and red creates a striking warning appearance.
Velvety Black Colour
The deep black body is responsible for the species’ common name:
Black Beauty Stick Insect.
Rather than attempting to resemble a thin brown twig, the species combines dark camouflage with conspicuous warning colours that become particularly obvious when disturbed.
Yellow Eyes
The pale yellow eyes contrast strongly with the black body.
This feature is present in both sexes and makes mature animals particularly distinctive.
Red Wings
Both sexes possess small, brilliantly coloured red hindwings.
These wings are used primarily as part of a defensive display.
They are not developed sufficiently for normal flight.
The Phasmid Study Group describes the species as possessing wings but being unable to fly or glide.
Can Black Beauty Stick Insects Fly?
No.
Despite possessing small wings, Peruphasma schultei is:
flightless.
The wings serve a defensive and visual function rather than allowing sustained flight.
This makes containment easier than with fully winged phasmids, although the insects remain capable climbers.
Adult Females
Adult females are larger and more heavily built than males.
The Phasmid Study Group records females at approximately:
55 mm in body length.
Females generally have:
- Broader abdomens
- Heavier bodies
- More robust proportions
Adult Males
Adult males are smaller and slimmer.
The Phasmid Study Group records males at approximately:
45 mm in body length.
Males tend to be:
- More slender
- More active
- Smaller overall
Once mature, the difference between the sexes is relatively straightforward to recognise.
Sexual Dimorphism
The physical differences between males and females are known as:
sexual dimorphism.
The sexes share the characteristic black, yellow and red colour scheme, but females are noticeably larger and broader.
Defensive Behaviour
Black Beauty Stick Insects possess several defensive strategies.
When disturbed they may:
- Freeze
- Move rapidly away
- Display their red wings
- Curve the abdomen
- Release defensive secretion
The combination of bright warning colours and chemical defence makes this species particularly interesting behaviourally.
Red-Wing Display
When threatened, an individual may suddenly expose its bright red hindwings.
The dramatic contrast between the:
black body and red wings
can function as a warning or startle display.
This behaviour should be observed naturally rather than deliberately provoked.
Chemical Defence
This is one of the most important aspects of Peruphasma schultei husbandry.
The species possesses defensive glands located behind the head.
When sufficiently disturbed, the insect can release a defensive liquid.
The Phasmid Study Group specifically lists:
chemical defence spray
as a warning for the species.
Defensive Secretion
The defensive compound produced by Peruphasma schultei has been chemically investigated and includes a compound known as:
peruphasmal.
Scientific analysis has identified this distinctive defensive compound in secretions from the species.
For the keeper, the exact chemistry is less important than understanding that the secretion should be treated with respect.
Eye Safety
Avoid allowing defensive secretion to contact:
- Eyes
- Mouth
- Nose
- Other sensitive tissues
Experienced breeders report that the secretion can irritate the eyes.
If an insect begins displaying strongly defensive behaviour, stop disturbing it and allow it to settle.
Handling
Black Beauty Stick Insects do not need regular handling.
Occasional careful handling may be possible, but because of their chemical defence they are better regarded primarily as:
display and observation animals.
If handling is necessary:
- Move slowly
- Allow the insect to walk onto your hand
- Avoid squeezing or restraining it
- Keep it away from your face
- Wash your hands afterwards
Children and Handling
Children should only interact with this species under responsible adult supervision.
The chemical defence makes casual unsupervised handling inappropriate.
The Phasmid Study Group specifically advises adult supervision when children handle phasmids and identifies chemical defence as a warning for this species.
Never Provoke the Defensive Spray
Do not deliberately:
- Poke the insect
- Squeeze it
- Blow repeatedly at it
- Restrain it
- Force the wing display
simply to demonstrate its defence.
Repeated defensive responses create unnecessary stress.
Housing
Black Beauty Stick Insects require an enclosure that is:
- Secure
- Well ventilated
- Tall enough for moulting
- Easy to clean
- Capable of retaining moderate humidity without becoming stagnant
Suitable housing includes:
- Mesh phasmid cages
- Partially screened terrariums
- Well-ventilated glass enclosures
- Well-ventilated plastic enclosures
Enclosure Size
The species is relatively small.
The Phasmid Study Group gives a minimum cage height of approximately:
17 cm.
However, there is little reason to restrict adults to the absolute minimum.
For a small group, an enclosure around:
30 × 30 × 40–45 cm
provides considerably more practical working space and generous moulting clearance.
Why Extra Space Helps
A larger enclosure provides:
- More feeding branches
- Additional moulting positions
- Better airflow
- Reduced crowding
- Easier maintenance
- More natural movement
Enclosure size should increase with colony size.
Moulting Height
Like other phasmids, Black Beauty Stick Insects must hang downward during moulting.
Provide enough vertical space for the insect to:
- Secure itself above the ground.
- Hang completely free.
- Exit the old exoskeleton.
- Extend its legs.
- Remain suspended while the new exoskeleton hardens.
Insufficient space can cause severe mismoults.
Three-Times Rule
A useful general phasmid guideline is to provide enclosure height of at least:
three times the insect’s body length.
For a 5.5 cm female, this means a minimum functional height of approximately 16.5 cm.
This closely corresponds with the Phasmid Study Group’s 17 cm minimum, but providing considerably more space is preferable.
Moulting Surfaces
Provide secure surfaces such as:
- Mesh
- Food branches
- Twigs
- Textured enclosure surfaces
The insect must be able to grip securely while moulting.
Clear Moulting Space
Do not fill every part of the enclosure with decorations.
Leave clear space beneath high branches and roof mesh.
A moulting insect should not collide with:
- The floor
- Food jars
- Decorations
- Other branches
while emerging.
Ventilation
Good ventilation is extremely important.
Experienced breeders specifically recommend an:
airy, well-ventilated cage
and warn against keeping the species excessively humid.
This is a particularly important distinction from species requiring persistently high humidity.
Partially Enclosed Housing
The Phasmid Study Group recommends partially enclosed housing, such as an enclosure with one full mesh side and other sides made from non-perforated glass or plastic.
This provides a useful compromise between:
- Airflow
- Humidity retention
- Security
Temperature
Black Beauty Stick Insects can generally be maintained at:
normal room temperature.
The Phasmid Study Group specifically lists room temperature for captive maintenance.
A practical range is approximately:
20–25°C.
Stable moderate conditions are preferable to excessive heat.
Heating
Many homes will not require additional heating.
If the room becomes consistently too cold, supplemental heating should be:
- Gentle
- External
- Thermostatically controlled
Never create an excessively hot or dry enclosure.
Direct Sunlight
Never place the enclosure in direct sunlight.
Glass and plastic enclosures can overheat rapidly.
Keep the enclosure away from:
- Sunny windows
- Radiators
- Powerful heat lamps
- Other uncontrolled heat sources
Humidity
Black Beauty Stick Insects appreciate moderate humidity but should not be kept excessively wet.
Published husbandry recommendations vary somewhat in exact percentages, which reflects differences between enclosure design and local conditions.
The important principle is:
moderate moisture + excellent ventilation.
Avoid permanently saturated conditions.
Misting
The Phasmid Study Group recommends lightly misting approximately:
every other day
to provide drinking water and maintain humidity.
Treat this as a starting point rather than an inflexible rule.
Actual frequency depends upon:
- Ventilation
- Room humidity
- Temperature
- Enclosure type
- Season
Do Not Soak the Enclosure
The enclosure should not remain:
- Waterlogged
- Permanently dripping
- Covered in heavy condensation
Experienced breeders specifically caution that the species should not be maintained at excessively high humidity.
Drinking
Light misting creates droplets that insects can drink from:
- Leaves
- Mesh
- Enclosure surfaces
Avoid blasting the insects directly with a spray bottle.
Water Bowls
Open water bowls are unnecessary and can create a drowning hazard.
Water used for keeping food branches fresh is the greater concern.
Food-Plant Water Containers
Cut food branches can be placed into water.
However, the opening must be securely blocked using:
- Cotton wool
- Foam
- Mesh
- Another safe barrier
Experienced breeders specifically warn that both nymphs and adults can drown in food-plant water containers.
Substrate
A complicated substrate is unnecessary.
Suitable flooring includes:
- Paper towel
- Plain paper
- Easily replaced liner
Paper is particularly convenient for breeding colonies.
Why Paper Flooring Works Well
Females drop their eggs onto the enclosure floor.
Paper makes it easier to:
- Find eggs
- Separate eggs from frass
- Monitor cleanliness
- Remove waste
- Detect mould
The Phasmid Study Group specifically recommends paper on the cage floor to simplify egg collection.
Furnishings
Useful enclosure furnishings include:
- Food branches
- Twigs
- Mesh climbing surfaces
- Secure branches
The species does not require elaborate decoration.
Practical climbing and moulting structures are more important.
Hiding Opportunities
Black Beauty Stick Insects can spend daylight hours concealed among foliage.
Dense food branches naturally provide:
- Shade
- Cover
- Resting surfaces
This allows the insects to choose sheltered positions during the day.
Diet
The most reliable captive food plant is:
privet (Ligustrum spp.).
The Phasmid Study Group lists privet as the food plant for Peruphasma schultei.
Privet should therefore be regarded as the safest starting food for a new colony.
Privet
Privet is particularly useful because many varieties are:
- Readily accepted
- Easy to identify once learned
- Common in cultivation
- Evergreen or semi-evergreen depending upon species and climate
This can make it an excellent year-round phasmid food.
Other Food Plants
Some captive stocks have also been maintained successfully on:
- Aucuba japonica
- Honeysuckle (Lonicera)
- Olive (Olea europaea)
- Bramble in some cultures and developmental stages
Experienced breeder records document these alternatives, although acceptance can vary between colonies.
Privet remains the most consistently established captive food.
Do Not Assume All Phasmid Foods Are Interchangeable
A food plant accepted by one stick insect species is not automatically suitable for another.
Do not assume that because another colony eats:
- Bramble
- Rose
- Oak
your Black Beauty Stick Insects will necessarily accept them.
Start with the food used successfully by the breeder.
Ask the Breeder
When obtaining new animals, ask:
What exact food plant are they currently eating?
Continue providing that food initially.
This is particularly important with young nymphs.
Natural Versus Captive Diet
In nature, Peruphasma schultei feeds on Schinus vegetation, while captive colonies are commonly maintained on Ligustrum.
This demonstrates that a captive substitute does not necessarily have to be the plant used in the wild, provided it is a well-established and nutritionally suitable food.
Food Plant Safety
All foliage must be free from harmful chemicals.
Never use plants that may have been exposed to:
- Insecticides
- Systemic pesticides
- Herbicides
- Other potentially harmful treatments
Pesticide exposure can kill phasmids rapidly.
Garden-Centre Plants
Do not assume newly purchased privet or other ornamental plants are immediately safe.
Commercial plants may have been treated with pesticides before purchase.
Unless treatment history is known, use foliage from an established safe source.
Systemic Pesticides
Systemic pesticides are absorbed into plant tissues.
Therefore:
washing does not make systemically treated foliage safe.
If you are uncertain about a plant’s chemical history, do not feed it.
Collecting Food Plants
Avoid collecting beside:
- Busy roads
- Agricultural fields
- Recently sprayed hedges
- Chemically managed public spaces
- Industrial areas
Establish reliable collection sites where pesticide exposure is unlikely.
Inspecting Foliage
Before adding branches, inspect them for:
- Spiders
- Predatory insects
- Caterpillars
- Snails
- Other unwanted invertebrates
Small predators can be particularly dangerous to hatchlings.
Washing Leaves
Rinsing foliage can help remove:
- Dirt
- Dust
- Loose contaminants
- Small organisms
Allow excess water to drain before use.
Again, washing cannot remove chemicals absorbed into plant tissues.
Keeping Food Fresh
Place cut stems into clean water.
Helpful practices include:
- Recutting stems
- Replacing water regularly
- Removing dead foliage
- Keeping plants away from excessive heat
Always cover the water-container opening.
Continuous Food
Fresh suitable foliage should remain available:
at all times.
Replace branches before all edible leaves become dry or completely wilted.
Activity
Black Beauty Stick Insects are primarily active during:
the evening and night.
During daylight they may remain relatively motionless among foliage.
After dark they become more active.
Daytime Behaviour
During daylight individuals may:
- Hide beneath leaves
- Remain motionless
- Rest in darker areas
- Depend upon camouflage
This behaviour is normal.
Night Behaviour
After dark they may:
- Feed
- Walk
- Explore
- Mate
- Change resting positions
Observing the enclosure after dark can reveal considerably more activity.
Moulting
Growth occurs through repeated moults.
Before moulting an insect may:
- Reduce feeding
- Become inactive
- Climb higher
- Hang beneath a branch or mesh surface
Leave it undisturbed.
During a Moult
Never handle an actively moulting insect.
The insect relies upon:
- Gravity
- Secure grip
- Adequate clearance
to remove itself from the old exoskeleton.
Disturbance can result in:
- Falls
- Trapped limbs
- Deformity
- Death
Freshly Moulted Insects
Immediately after moulting, the insect is soft and vulnerable.
Allow the new exoskeleton to harden naturally.
Do not attempt to handle a freshly moulted animal simply because its colour looks unusual.
Exuvia
The discarded exoskeleton is called the:
exuvia.
The insect may consume some or all of it.
This is normal behaviour.
Failed Moults
Possible contributing factors include:
- Insufficient vertical space
- Poor grip
- Physical obstruction
- Dehydration
- Excessive disturbance
- Inappropriate environmental conditions
- Overcrowding
Correct enclosure design is the best preventative measure.
Limb Loss
Like other phasmids, juveniles can sometimes lose limbs through:
- Accidents
- Falls
- Entrapment
- Poor handling
- Moulting problems
Never pull an insect from a branch while it is gripping.
Limb Regeneration
Young phasmids may regenerate missing limbs over subsequent moults.
A replacement limb can initially be:
- Smaller
- Shorter
- Less developed
Further moults may improve its appearance and function.
Adults with no remaining moults cannot regenerate limbs in the same way.
Nymphs
Newly hatched Black Beauty Stick Insects are much smaller and more delicate than adults.
They require:
- Secure housing
- Fine ventilation
- Fresh accepted food
- Appropriate moisture
- Good airflow
- Moulting space
Nymph Housing
A dedicated rearing enclosure can make hatchlings easier to manage.
It should provide:
- Fine escape-proof ventilation
- Tender food
- Secure climbing surfaces
- Drinking droplets
- Vertical moulting clearance
Escape Prevention
Tiny nymphs can fit through gaps that easily contain adults.
Inspect:
- Door gaps
- Mesh size
- Ventilation openings
- Lid edges
- Cable holes
before eggs begin hatching.
Feeding Nymphs
Offer the same proven food plant used by the breeder.
Privet is the established standard.
Fresh tender foliage can be particularly useful for small nymphs.
Encouraging Initial Feeding
If newly hatched nymphs have difficulty beginning to feed, lightly trimming the edges of suitable leaves can expose fresh plant tissue.
Do not interfere if clear feeding damage is already visible.
Social Housing
Black Beauty Stick Insects can generally be maintained communally.
Provide enough:
- Food
- Space
- Climbing surfaces
- Moulting positions
for every individual.
Overcrowding
Overcrowding increases the risk of:
- Moulting interference
- Falls
- Limb damage
- Food shortages
- Excessive waste
- Stress
Divide colonies as numbers increase.
Mixed-Species Housing
Routine mixed-species housing is not recommended.
Different phasmids can have different requirements for:
- Food
- Humidity
- Temperature
- Ventilation
The defensive secretion of Peruphasma schultei provides an additional reason to maintain the species separately.
Reproduction
Black Beauty Stick Insects reproduce:
sexually.
Both males and females are required for normal production of fertilised eggs.
The Phasmid Study Group specifically records reproduction as sexual.
Is the Species Parthenogenetic?
Unlike several commonly kept phasmids, Peruphasma schultei should not be treated as a normally parthenogenetic species.
For reliable breeding, maintain:
males and females.
Mating
Males may remain attached to females for extended periods.
This is normal reproductive behaviour.
Avoid unnecessarily separating a mating pair.
Egg Laying
Females generally:
drop their eggs onto the enclosure floor.
No specialised egg-laying container is required.
The Phasmid Study Group specifically records eggs being dropped onto the cage floor.
Egg Collection
Paper flooring makes egg collection straightforward.
During routine cleaning:
- Remove excessive frass.
- Locate eggs.
- Separate eggs intended for incubation.
- Replace dirty paper.
- Manage unwanted eggs responsibly.
Egg Incubation
Eggs can be incubated separately in a:
ventilated container.
They should not be kept excessively wet.
Experienced breeders report that the eggs tolerate relatively dry conditions and caution against excessively humid incubation.
Incubation Moisture
The objective is:
moderate moisture without saturation.
Avoid:
- Waterlogging
- Constant heavy condensation
- Permanently wet eggs
Ventilation remains important.
Incubation Temperature
Normal warm room temperatures are generally suitable.
Approximately:
20–25°C
provides a practical range.
Avoid extreme heat in an attempt to accelerate development.
Incubation Time
The Phasmid Study Group gives an incubation period of approximately:
3–6 months.
Other experienced breeders commonly report around three to four months under their particular conditions.
Variation is therefore normal.
Hatching Success
The Phasmid Study Group lists an approximate ova success rate of:
60–80%.
Not every apparently normal egg should be expected to hatch.
Staggered Hatching
Eggs from the same group may hatch at different times.
Do not discard apparently healthy eggs merely because others have already hatched.
Continue appropriate incubation unless there are clear signs of deterioration.
Hatchlings
Prepare nymph housing before hatching begins.
Newly emerged nymphs should have immediate access to:
- Fresh privet or another established food
- Climbing surfaces
- Drinking droplets
- Appropriate ventilation
- Moulting clearance
Growth
Development speed depends upon:
- Temperature
- Food quality
- Individual genetics
- General husbandry
Experienced breeder records report approximately five months from nymph to adult under some captive conditions.
Individual development can vary.
Adult Longevity
Black Beauty Stick Insects can be relatively long-lived for phasmids of their size.
Lifespan varies with:
- Sex
- Temperature
- Reproductive activity
- Nutrition
- Individual condition
Females generally outlive males.
Population Management
Because sexual reproduction requires both sexes, population growth is easier to control than in highly productive parthenogenetic species.
Nevertheless, successful colonies can produce substantial numbers of eggs.
Only incubate the number you can realistically:
- House
- Feed
- Maintain
- Rehome responsibly
Unwanted Eggs
Do not simply discard viable eggs outdoors.
They should be managed so they cannot hatch into the environment.
Never place potentially viable eggs into:
- Gardens
- Outdoor compost
- Natural vegetation
Follow applicable local environmental and welfare requirements.
Never Release Captive Phasmids
Never release:
- Adults
- Nymphs
- Eggs
into the wild.
This applies regardless of whether you believe local weather conditions would prevent establishment.
Health
Most health problems encountered in captive Black Beauty Stick Insects are related to husbandry.
Important risks include:
- Mismoults
- Dehydration
- Excessive humidity
- Poor ventilation
- Pesticide exposure
- Overheating
- Limb injury
- Overcrowding
Warning Signs
Potential reasons for concern include:
- Repeated falling
- Inability to grip
- Severe mismoults
- Persistent weakness
- Loss of coordination
- Unusual immobility combined with deterioration
- Failure to feed over an extended period
Remember that temporary reduced feeding before moulting can be normal.
Pesticide Exposure
Possible signs of pesticide poisoning can include:
- Trembling
- Loss of coordination
- Poor grip
- Falling
- Rapid deterioration
Treatment options for severe insecticide exposure are extremely limited.
Prevention through safe food sourcing is essential.
Cleaning
Routine maintenance should include:
- Removing excessive frass
- Removing dead foliage
- Replacing food branches
- Cleaning plant-water containers
- Replacing dirty flooring
- Removing mould
Avoid disturbing insects that are actively moulting.
Egg Checks During Cleaning
Because eggs are dropped onto the floor, always inspect enclosure waste before disposal.
Eggs can become mixed with:
- Frass
- Dead leaves
- Paper
- Other debris
Household Chemicals
Keep the enclosure well away from:
- Fly spray
- Flea treatments
- Ant killer
- Garden pesticides
- Aerosol insecticides
A well-ventilated phasmid enclosure provides very little protection from airborne chemicals.
Aerosols
Avoid spraying close to the enclosure:
- Air fresheners
- Cleaning aerosols
- Perfume
- Deodorising products
Minimising airborne chemical exposure is sensible for all captive invertebrates.
Quarantine
New insects should ideally be maintained separately before joining an established colony.
Observe:
- Feeding
- Moulting
- General condition
- Food acceptance
- Potential unwanted organisms
Quarantine also provides an opportunity to confirm sex and species identification.
Captive-Bred Animals
Captive-bred Black Beauty Stick Insects should be strongly preferred.
The species is established in captive culture and reproduces readily when both sexes are maintained.
Captive-bred stock provides:
- Better provenance
- Known feeding history
- Reduced pressure on wild populations
Responsible Sourcing
Before obtaining Peruphasma schultei, ask the breeder:
- What food plant are they currently eating?
- What age or instar are they?
- What sex are they, if known?
- Are both sexes available if breeding is intended?
- When were purchased eggs laid?
The food-plant question is particularly important.
Legal Considerations
Regulations concerning phasmids vary significantly between jurisdictions.
Restrictions may apply to:
- Possession
- Breeding
- Sale
- Transport
- Import
- Export
Non-native plant-eating insects can be subject to agricultural or environmental controls.
Always check current legislation applicable to your location.
Common Husbandry Mistakes
Common mistakes include:
- Keeping the enclosure too wet
- Providing poor ventilation
- Insufficient moulting height
- Feeding unsuitable foliage
- Using pesticide-treated plants
- Leaving food-plant water containers uncovered
- Pulling insects from branches
- Handling during moulting
- Deliberately provoking defensive behaviour
- Allowing defensive secretion near the eyes
- Assuming the species reproduces parthenogenetically
- Overcrowding
- Incubating more eggs than can be accommodated
- Accidentally disposing of viable eggs outdoors
Most of these problems are easily preventable.
Are Black Beauty Stick Insects Suitable for Beginners?
Generally:
Yes, for a well-informed beginner.
The Phasmid Study Group rates the species as easy.
Advantages include:
- Small adult size
- Room-temperature husbandry
- Straightforward breeding
- Privet as a practical food plant
- Flightlessness
- Striking appearance
However, beginners must understand two particularly important requirements:
do not keep them excessively wet, and respect their chemical defence.
Why This Species Is Different
Many commonly kept phasmids rely almost entirely upon camouflage.
Peruphasma schultei combines:
- Dark camouflage
- Bright warning colours
- A red-wing startle display
- Chemical defence
This makes it an especially interesting species for observing insect defensive biology.
Educational Value
Black Beauty Stick Insects provide excellent opportunities to observe:
- Warning colouration
- Chemical defence
- Defensive wing displays
- Sexual dimorphism
- Moulting
- Incomplete metamorphosis
- Herbivory
- Sexual reproduction
- Egg development
They demonstrate particularly well that stick insects are considerably more diverse than simple twig mimics.
Responsible Ownership
Before obtaining Black Beauty Stick Insects, ensure you can provide:
- Reliable pesticide-free privet or another proven food plant
- A well-ventilated enclosure
- Appropriate moderate humidity
- Adequate moulting space
- Safe handling procedures
- Responsible egg management
- Housing for offspring if breeding
The defensive secretion should also be considered when deciding whether the species is appropriate for a household with young children.
Summary
The Black Beauty Stick Insect (Peruphasma schultei) is a spectacular small phasmid from Peru characterised by a velvety black body, pale yellow eyes and brilliant red hindwings.
Despite possessing wings, the species cannot fly. The red hindwings instead form part of an impressive defensive display.
The species’ most important special characteristic is its chemical defence. When threatened, individuals can release defensive secretion from glands behind the head. The secretion can irritate sensitive tissues, particularly the eyes, so handling should remain limited and deliberate provocation should always be avoided.
Successful husbandry requires a secure and very well-ventilated enclosure, moderate humidity, normal warm room temperatures, sufficient moulting clearance and continuous access to fresh pesticide-free foliage.
Privet (Ligustrum spp.) is the principal established captive food plant and is specifically recommended by the Phasmid Study Group.
Unlike several other commonly kept stick insects, Peruphasma schultei reproduces sexually. Both males and females are therefore required for reliable breeding. Females drop their eggs onto the enclosure floor, where they can be collected easily when paper flooring is used.
Egg incubation commonly takes approximately 3–6 months, and eggs should be maintained with good ventilation without excessively wet conditions.
With appropriate ventilation, safe food plants, adequate moulting space and respect for its defensive capabilities, Peruphasma schultei is a manageable and exceptionally distinctive captive phasmid.
IMPORTANT INFORMATION
This care sheet provides general husbandry guidance and does not replace current species-specific research or applicable wildlife, agricultural and import legislation.
Peruphasma schultei possesses a chemical defensive spray. Avoid deliberately provoking defensive behaviour and prevent the secretion from contacting the eyes, mouth or other sensitive tissues.
Food plants must be correctly identified and completely free from pesticides, herbicides and other harmful chemical treatments. Washing foliage does not make systemically treated plants safe.
Privet (Ligustrum spp.) is the principal established captive food plant.
Provide excellent ventilation and avoid excessively wet, stagnant conditions.
Always provide sufficient unobstructed vertical space for moulting and never disturb an insect actively shedding its exoskeleton.
This species reproduces sexually, so males and females are required for reliable breeding.
Never release captive adults, nymphs or eggs into the environment.
Always verify current regulations concerning possession, breeding, sale, transport, import and export in your jurisdiction.
