Indian Stick Insect (Carausius morosus) Care Sheet
The Indian Stick Insect is one of the best-known and most widely kept phasmids in captivity. Carausius morosus is a slender, plant-feeding stick insect originally associated with southern India and has been maintained in captive cultures for generations.
Its relatively straightforward husbandry, calm behaviour and fascinating camouflage make it an excellent introductory species. However, “easy to keep” does not mean that its requirements can be ignored. Indian Stick Insects need fresh pesticide-free food plants, excellent ventilation, appropriate humidity and, most importantly, sufficient vertical space to moult safely.
The species is particularly notable for its reproductive biology. Captive populations consist overwhelmingly of females, which can reproduce without mating through parthenogenesis. A single adult female can therefore produce large numbers of viable eggs without ever encountering a male.
For this reason, population management is an important and often underestimated part of responsible Indian Stick Insect husbandry.

Natural Distribution
Carausius morosus originates from southern India.
Long-established captive populations are now maintained throughout much of the world.
Because this species has been kept and bred in captivity for many generations, animals encountered within the hobby are generally captive-bred rather than recently collected from the wild.
Natural Lifestyle
Indian Stick Insects are arboreal herbivores.
Their lives revolve around vegetation, where they:
- Feed on leaves
- Rest among stems
- Climb
- Hide through camouflage
- Hang during moulting
Their elongated body shape allows them to resemble thin twigs remarkably effectively.
Appearance
Adults are long and slender with:
- Narrow elongated bodies
- Long legs
- Long antennae
- Small heads
- Wingless bodies
- Twig-like colouration
Colour varies between individuals.
Colour
Indian Stick Insects may appear:
- Green
- Olive
- Brown
- Greyish brown
- Mottled
Individuals can sometimes change somewhat in appearance as they grow and moult.
Colour is influenced by several factors including genetics and environmental conditions.
Adult Size
Adult females commonly reach approximately:
8–10 cm in body length.
Their long legs make their total apparent size considerably greater.
They are much slimmer and lighter than species such as the Giant Prickly Stick Insect.
Lifespan
Under suitable captive conditions, an Indian Stick Insect may live for approximately:
9–18 months
from hatching through adulthood.
Individual lifespan varies according to:
- Temperature
- Nutrition
- Moulting success
- Genetics
- Reproductive output
Females
Almost all Indian Stick Insects encountered in established captive cultures are:
female.
Females can mature and reproduce without mating.
This makes maintaining the species extremely easy but can also result in unexpectedly large populations.
Males
Males are extremely uncommon in captive populations.
Occasional males have been reported, but a keeper should not expect to require a male in order to breed the species.
A colony consisting entirely of females can continue reproducing for generation after generation.
Wingless Species
Indian Stick Insects are wingless.
They cannot fly.
However, they are excellent climbers and can move surprisingly quickly when disturbed.
A secure enclosure is still necessary.
Housing
A tall, well-ventilated enclosure is required.
Suitable housing can include:
- Mesh phasmid cages
- Tall insect terrariums
- Well-ventilated plastic enclosures
- Purpose-built stick insect cages
The enclosure must provide:
- Vertical height
- Good airflow
- Climbing surfaces
- Fresh food plants
- Moulting space
- Secure containment
Enclosure Size
For a small group of adults, approximately:
30 × 30 × 45 cm or larger
provides a useful starting point.
Larger colonies require additional space.
Height is more important than excessive floor area.
Moulting Height
A useful minimum rule for phasmids is to provide enclosure height of at least:
three times the insect’s body length.
This must include clear hanging space beneath suitable moulting surfaces.
More height is preferable.
Why Height Matters
Stick insects moult while hanging vertically.
During a successful moult, the insect:
- Anchors itself above the ground.
- Splits the old exoskeleton.
- Pulls itself downward.
- Extracts the legs and body.
- Hangs freely.
- Expands the new exoskeleton.
- Hardens before moving normally.
Without enough clearance, the insect can become permanently deformed or die.
Clear Moulting Space
Do not fill the enclosure so densely with branches and decorations that insects cannot hang freely.
There should be unobstructed space beneath:
- The enclosure roof
- Mesh panels
- Upper branches
A moulting insect must not collide with the floor or furnishings.
Ventilation
Excellent ventilation is essential.
Poor airflow combined with excessive moisture can encourage:
- Mould
- Stagnant conditions
- Bacterial growth
- Husbandry problems
Mesh enclosures are particularly useful.
Mesh Enclosures
Mesh cages provide:
- Excellent ventilation
- Extensive climbing surfaces
- Good moulting surfaces
- Easy attachment points for foliage
They can dry more quickly than glass enclosures, so moisture levels should still be monitored.
Glass or Plastic Enclosures
Solid-sided enclosures can be used if they provide substantial ventilation.
A sealed container with a few tiny ventilation holes is unsuitable.
Cross-ventilation is particularly beneficial.
Secure Lid
Indian Stick Insects are excellent climbers.
Ensure that:
- Doors close securely
- Mesh is intact
- Cable gaps are sealed
- Nymphs cannot escape through ventilation openings
Tiny newly hatched nymphs require much finer escape prevention than adults.
Temperature
A useful general temperature range is approximately:
18–25°C.
Normal indoor temperatures are often suitable.
They do not generally require very high tropical temperatures.
Ideal Household Conditions
Many colonies thrive at approximately:
20–24°C.
Avoid prolonged exposure to:
- Excessive heat
- Cold drafts
- Extreme temperature fluctuations
Heating
Supplemental heating is often unnecessary.
If additional heat is required, use:
- Gentle external heating
- Thermostatic control
- A safe temperature gradient
Do not allow heaters to dry the enclosure excessively.
Direct Sunlight
Never place the enclosure in direct sunlight.
Transparent enclosures can overheat rapidly.
Keep the enclosure away from:
- Sunny windows
- Radiators
- Strong heat sources
Humidity
Moderate humidity is appropriate.
A useful general range is approximately:
60–75% relative humidity
provided there is excellent ventilation.
Constantly wet conditions are unnecessary and potentially harmful.
Misting
Light misting can be used to provide:
- Drinking droplets
- Temporary humidity
- Support around moulting
Depending upon ventilation and room conditions, light misting every day or every few days may be appropriate.
Allow the enclosure to dry somewhat between misting.
Drinking
Indian Stick Insects commonly drink droplets from:
- Leaves
- Mesh
- Enclosure surfaces
Lightly misting the foliage provides drinking opportunities.
Do not spray insects heavily at close range.
Open Water
Avoid accessible deep water containers.
Stick insects, particularly tiny nymphs, can drown.
Water used to keep cut food plants fresh must be safely covered.
Covering Plant Containers
Place cut plant stems into water and cover the opening around them with:
- Foam
- Mesh
- Cotton wool
- Another secure material
Only the stems should pass through.
No insect should be able to fall into the water.
Substrate
Complicated substrate is unnecessary.
Suitable enclosure flooring includes:
- Paper towel
- Plain paper
- Easily cleaned liner
- Thin natural substrate
For breeding colonies, paper makes egg management considerably easier.
Paper Towel
Paper towel is an excellent practical choice.
It allows the keeper to:
- See eggs
- See frass
- Monitor cleanliness
- Replace the floor easily
This is particularly useful because females can produce enormous numbers of eggs.
Naturalistic Substrate
Natural substrate can be used.
However, eggs become much harder to locate.
If using soil or another loose substrate, assume viable eggs may be hidden throughout it.
Never dispose of used substrate outdoors without considering this.
Climbing Surfaces
Food branches usually provide much of the required climbing structure.
Additional options include:
- Safe twigs
- Mesh walls
- Branches
Ensure upper surfaces allow secure hanging for moulting.
Diet
Indian Stick Insects are herbivorous.
They require fresh leaves from suitable food plants.
Commonly accepted plants include:
- Bramble
- Privet
- Ivy
- Rose
- Hawthorn
- Raspberry
Food acceptance can vary between captive lines.
Bramble
Bramble is one of the most useful staple foods.
Blackberry leaves are particularly convenient because they are:
- Widely available
- Usually evergreen or semi-evergreen in many areas
- Readily accepted
- Easy to place in water
Correct identification and pesticide safety remain essential.
Privet
Privet is commonly accepted by Indian Stick Insects.
Only use correctly identified plants that have not been treated with:
- Insecticides
- Herbicides
- Other harmful chemicals
Do not assume ornamental garden plants are pesticide-free.
Ivy
Ivy is accepted by many Carausius morosus colonies.
However, when receiving insects from another keeper, it is sensible to continue offering the food plant they are already accustomed to while introducing alternatives.
Rose
Unsprayed rose can be offered.
Avoid commercially produced florist or garden-centre roses unless their chemical history is known.
Many ornamental plants are treated with systemic insecticides.
Hawthorn
Hawthorn may also be accepted.
Only collect from safe areas away from:
- Road pollution
- Pesticide use
- Agricultural spraying
Correct plant identification is essential.
Food Plant Safety
The most important rule regarding food is:
never feed foliage that may have been treated with pesticides.
Stick insects are extremely sensitive to insecticides.
A contaminated food plant can kill an entire colony.
Systemic Pesticides
Systemic pesticides are absorbed into the plant itself.
This means:
washing the leaves does not make a systemically treated plant safe.
If you do not know the plant’s treatment history, do not feed it.
Wild Collection
When collecting wild food plants, avoid:
- Busy roadsides
- Agricultural field margins
- Public areas regularly sprayed
- Industrial locations
- Recently managed vegetation
Choose clean, uncontaminated locations.
Washing Foliage
Rinsing leaves before use can remove:
- Dirt
- Dust
- Surface contamination
- Other small animals
Inspect foliage carefully before placing it into the enclosure.
Other Invertebrates on Food Plants
Wild foliage can accidentally introduce:
- Spiders
- Predatory bugs
- Caterpillars
- Beetles
- Other insects
Inspect branches carefully.
A small predatory spider can be dangerous to young stick insects.
Keeping Food Fresh
Cut stems should be placed into water.
For best results:
- Recut stems
- Use clean water
- Replace water regularly
- Remove dead foliage
- Keep the water container covered
Fresh foliage should remain continuously available.
Food Replacement
Replace leaves before they become:
- Completely wilted
- Dry
- Mouldy
- Unpalatable
Do not allow the colony to run out of edible foliage.
Changing Food Plants
When introducing a new plant, offer it alongside a familiar accepted food.
This is particularly useful for newly acquired insects.
Do not abruptly remove the only food plant they are known to eat.
Feeding Signs
Evidence of feeding includes:
- Missing leaf edges
- Small holes
- Fresh frass beneath feeding areas
Tiny nymphs eat very small amounts, so feeding damage may initially be difficult to see.
Frass
Stick insect droppings are called:
frass.
Indian Stick Insect frass usually appears as small dark pellets.
Remove excessive accumulations during routine cleaning.
Lighting
Specialised lighting is generally unnecessary.
A normal day/night cycle is sufficient.
Ambient room lighting usually provides adequate environmental cues.
UVB
UVB lighting is not generally required.
If additional plant or display lighting is used, ensure that it does not:
- Overheat the enclosure
- Dry foliage excessively
- Eliminate normal darkness at night
Activity
Indian Stick Insects are primarily:
nocturnal.
During daylight they often remain motionless.
After dark they become more active and may:
- Feed
- Walk
- Explore
- Change resting positions
Swaying
A disturbed stick insect may sway gently from side to side.
This is normal.
The movement can imitate:
a twig moving in the wind.
It forms part of the species’ camouflage strategy.
Defensive Behaviour
Indian Stick Insects rely heavily upon:
- Camouflage
- Remaining motionless
- Swaying
- Dropping from vegetation
They are not aggressive.
Thanatosis
When severely disturbed, an individual may become rigid and motionless.
This behaviour resembles death and can help discourage predators.
Do not assume a completely still insect is dead without careful observation.
Handling
Indian Stick Insects can tolerate occasional gentle handling.
However, their legs are delicate.
The safest method is to:
allow the insect to walk onto your hand voluntarily.
Never Pull a Stick Insect
Never pull an insect from:
- Mesh
- A branch
- Clothing
- Another surface
Its feet may remain firmly attached while the body is pulled away, resulting in leg loss.
Encourage each foot to release naturally.
Handling Nymphs
Young nymphs are particularly fragile.
Avoid handling unless necessary.
For transfers, encourage them onto:
- A leaf
- Twig
- Soft brush
rather than gripping them directly.
Falls
Stick insects are lightweight, but falls can still cause injury.
Handle them:
- Close to a surface
- Indoors
- Away from pets
- Away from open windows
Never throw or drop an insect onto vegetation.
Autotomy
Stick insects can sometimes deliberately shed a trapped or damaged limb.
This is called:
autotomy.
It can help the insect escape from a predator.
Limb Regeneration
Young stick insects can regenerate lost limbs during subsequent moults.
A replacement limb may initially be smaller.
After additional moults, it may become progressively more functional.
Adult insects cannot regenerate a limb once no further moults remain.
Moulting
Stick insects grow by shedding their exoskeleton.
This process is called:
ecdysis, or moulting.
It is one of the most vulnerable periods of their lives.
Signs of an Approaching Moult
Before moulting, an insect may:
- Stop eating
- Become less active
- Select a high position
- Hang beneath a surface
Do not disturb it.
During the Moult
The insect hangs from its old exoskeleton and slowly pulls itself free.
It requires:
unobstructed vertical clearance.
Never touch an actively moulting insect.
Failed Moults
Potential causes include:
- Insufficient enclosure height
- Poor hanging surfaces
- Disturbance
- Dehydration
- Inappropriate humidity
- Overcrowding
- Physical obstruction
Severe moulting failures can be fatal.
Freshly Moulted Insects
Immediately after moulting, the new exoskeleton is soft.
The insect may appear:
- Pale
- Bright green
- Weak
- Unusually delicate
Allow several hours for hardening before disturbing it.
Exuvia
The discarded exoskeleton is called the:
exuvia.
An insect may consume some of it after moulting.
This is normal and recycles nutrients.
Nymph Development
Young insects pass through several developmental stages known as:
instars.
Each instar ends with a moult.
With every successful moult, the insect becomes larger and more adult-like.
Newly Hatched Nymphs
Newly hatched nymphs are:
- Small
- Thin
- More active than adults
- Capable climbers
Their tiny size makes escape prevention particularly important.
Nymph Housing
Nymphs require:
- Fine escape-proof ventilation
- Fresh tender foliage
- Suitable humidity
- Excellent airflow
- Adequate moulting height
Do not overcrowd them.
Nymph Escape Prevention
A ventilation gap that easily contains an adult may allow a newly hatched nymph to escape.
Check:
- Mesh size
- Door gaps
- Lid edges
- Cable holes
before eggs begin hatching.
Nymph Feeding
Young nymphs can eat the same suitable food plants as adults.
Tender fresh leaves are particularly useful.
Ensure food is easy to reach from the enclosure walls and climbing surfaces.
Encouraging Newly Hatched Nymphs to Feed
If necessary, lightly trimming leaf edges can expose fresh plant tissue.
This may help very young nymphs recognise feeding sites.
If normal feeding damage is already present, intervention is unnecessary.
Social Housing
Indian Stick Insects can be maintained communally.
Groups should have:
- Adequate enclosure volume
- Abundant food
- Multiple climbing surfaces
- Sufficient moulting space
Social housing does not mean overcrowding is acceptable.
Overcrowding
Overcrowding can result in:
- Interrupted moults
- Limb damage
- Falls
- Food shortages
- Excessive waste
- Constant disturbance
Reduce colony density as numbers increase.
Mixed-Species Housing
Keeping multiple phasmid species together is generally unnecessary.
Different species can have different requirements and may interfere with one another during moulting.
Species-specific housing is easier to manage safely.
Reproduction
Reproduction is one of the most remarkable aspects of Carausius morosus.
Captive females usually reproduce by:
parthenogenesis.
This means they can produce viable eggs without mating.
Parthenogenesis
Parthenogenesis is reproduction from an unfertilised egg.
No male is required.
As a result, a keeper beginning with a single female can eventually develop a large colony.
Parthenogenetic Offspring
Offspring produced through the usual captive parthenogenetic reproduction are overwhelmingly:
female.
This explains why males are extraordinarily uncommon in captive colonies.
Egg Production
Adult females can lay eggs regularly for many months.
A single female may produce:
hundreds of eggs during her lifetime.
This is why population control should be planned before the first female reaches maturity.
Egg Laying
Females simply drop their eggs onto the enclosure floor.
They do not usually attach them carefully to leaves or bury them.
Eggs become mixed with:
- Frass
- Dead leaves
- Other enclosure debris
Regular collection is therefore useful.
Appearance of Eggs
Indian Stick Insect eggs are small and seed-like.
They are generally:
- Brownish
- Rounded or oval
- Hard-shelled
They can initially be mistaken for droppings.
Eggs vs Frass
With experience, eggs are easy to distinguish from frass.
Eggs have:
- A more consistent shape
- A hard shell
- A distinct cap-like structure
Frass is generally less structured.
Egg Collection
Using paper towel or plain paper as the enclosure floor makes eggs much easier to locate.
Eggs can be collected during routine cleaning.
Only incubate the number that can realistically be housed.
Egg Incubation
Eggs can be incubated in a small ventilated container.
Suitable methods include placing them on:
- Slightly moist vermiculite
- Slightly moist substrate
- Appropriate paper-based incubation material
Good airflow is important.
Incubation Humidity
Eggs require moderate humidity but should not remain wet.
Avoid:
- Standing water
- Permanently saturated substrate
- Heavy condensation
Excess moisture encourages mould.
Incubation Temperature
Normal room temperatures around:
20–24°C
are generally appropriate.
Avoid attempts to force faster development through excessive heat.
Incubation Time
Indian Stick Insect eggs can take:
several months
to hatch.
Approximately 2–6 months is common under suitable conditions, although individual eggs can take longer.
Do not discard healthy-looking eggs simply because they have not hatched at exactly the same time as others.
Staggered Hatching
Eggs laid together may hatch at different times.
Maintain the incubation container while viable-looking eggs remain.
Check regularly for newly emerged nymphs.
Hatchlings
Newly hatched nymphs should be transferred carefully to a suitable rearing enclosure.
Provide:
- Fine ventilation
- Tender food plants
- Drinking droplets
- Adequate height
- Safe climbing surfaces
Population Explosion
This species can reproduce remarkably efficiently.
For example, several mature females continuously producing viable eggs can create:
hundreds or potentially thousands of offspring over time.
Do not incubate every egg unless there is a genuine plan for the resulting insects.
Population Control
Responsible population management is essential.
Options include:
- Incubating only selected eggs
- Separating eggs during cleaning
- Preventing unwanted eggs from developing using an appropriate humane method
- Rehoming manageable numbers responsibly
Never release unwanted insects.
Managing Unwanted Eggs
Unwanted viable eggs must be disposed of in a way that ensures they cannot hatch into the environment.
Methods should comply with local animal-welfare and environmental regulations.
Do not simply throw viable eggs:
- Into gardens
- Into outdoor compost
- Onto vegetation
Breeding Records
For larger colonies, simple records can be useful.
Record:
- Approximate hatch dates
- Adult maturation
- Egg collection dates
- Incubation batches
- Food plants used
This makes population management considerably easier.
Health
Common husbandry-related problems include:
- Failed moults
- Dehydration
- Limb loss
- Pesticide poisoning
- Overheating
- Poor ventilation
- Overcrowding
Many serious problems are preventable.
Warning Signs
Possible reasons for concern include:
- Repeated falls
- Inability to grip
- Severe limb deformities
- Incomplete moults
- Persistent weakness
- Failure to feed combined with deterioration
Temporary fasting immediately before moulting is normal.
Pesticide Poisoning
Possible signs following exposure to contaminated foliage may include:
- Loss of coordination
- Trembling
- Falling
- Inability to grip
- Rapid colony-wide deterioration
Prevention is critical because treatment options are extremely limited.
Never use questionable foliage.
Cleaning
Routine cleaning should include:
- Removing excessive frass
- Removing dead foliage
- Replacing paper flooring
- Cleaning plant-water containers
- Removing mould
Avoid disturbing insects that are moulting.
Cleaning Around Eggs
Before throwing away enclosure waste, inspect it for eggs.
This includes:
- Paper towel
- Leaf litter
- Frass
- Dead foliage
A large proportion of eggs can otherwise be discarded accidentally.
Chemical Sensitivity
Indian Stick Insects are highly vulnerable to insecticides.
Keep them away from:
- Fly spray
- Flea treatments
- Ant killer
- Household insecticide
- Garden pesticides
- Treated ornamental plants
Do not spray chemicals in the same room as an open or highly ventilated enclosure.
Air Fresheners and Aerosols
Avoid spraying strong aerosols near the enclosure.
This includes:
- Air freshener
- Cleaning sprays
- Perfume
- Deodorising sprays
- Pesticides
A mesh enclosure offers little protection from airborne chemicals.
Quarantine
New stick insects should ideally be maintained separately before joining an established colony.
This allows monitoring of:
- Feeding
- Moulting
- General condition
- Potential parasites
- Food-plant preferences
Captive-Bred Animals
Indian Stick Insects have been maintained in captivity for generations.
Captive-bred animals should be the normal choice.
There is no need to encourage unnecessary wild collection for an easily reproduced species.
Responsible Sourcing
Before obtaining insects or eggs, ask:
- What food plant are they currently eating?
- What developmental stage are they?
- Are they captive-bred?
- When did eggs approximately hatch?
- What conditions have they been maintained under?
Knowing the established food plant is particularly valuable for young nymphs.
Legal Considerations
Regulations concerning stick insects vary between jurisdictions.
Because they are plant-eating non-native insects, some countries or regions strictly regulate:
- Possession
- Breeding
- Sale
- Transport
- Import
- Export
Never assume that a commonly kept species is automatically legal everywhere.
Invasive Potential
Indian Stick Insects should never be introduced into environments outside their permitted captive setting.
Their ability to:
- Eat a range of plants
- Reproduce without males
- Produce large numbers of eggs
makes accidental establishment a legitimate environmental concern in suitable climates.
Never Release Captive Stick Insects
Never release:
- Adults
- Nymphs
- Eggs
into the wild.
This applies even if the species appears unlikely to survive locally.
Responsible rehoming or appropriate humane management is required.
Disposal of Used Substrate
Any used enclosure material may contain eggs.
Before disposal:
- Inspect it carefully
- Separate visible eggs
- Ensure unwanted eggs cannot subsequently hatch outdoors
This is especially important when natural substrate is used.
Common Husbandry Mistakes
Common mistakes include:
- Enclosures that are too short
- Insufficient moulting clearance
- Poor ventilation
- Excessive humidity
- Allowing foliage to dry out
- Feeding pesticide-treated plants
- Leaving open water containers
- Pulling insects from branches
- Handling moulting insects
- Overcrowding
- Ignoring egg production
- Assuming females require males to reproduce
- Releasing unwanted offspring
Most of these problems are straightforward to prevent.
Are Indian Stick Insects Suitable for Beginners?
Generally:
Yes.
Carausius morosus is one of the classic beginner phasmids.
Advantages include:
- Straightforward feeding
- No venom
- No functional wings
- Calm behaviour
- Easy breeding
- Modest temperature requirements
However, new keepers must understand the importance of:
moulting height, pesticide-free foliage and population control.
Educational Value
Indian Stick Insects are excellent animals for demonstrating:
- Camouflage
- Herbivory
- Incomplete metamorphosis
- Moulting
- Limb regeneration
- Parthenogenesis
- Insect growth
Their relatively straightforward husbandry makes them particularly useful for educational observation.
Responsible Ownership
Before obtaining Indian Stick Insects, consider:
- Availability of safe food plants year-round
- Need for a tall enclosure
- Vulnerability during moulting
- Extremely high reproductive potential
- Requirement for egg management
- Local regulations
The biggest challenge is often not keeping them alive.
It is preventing a handful of insects from becoming hundreds of insects.
Summary
The Indian Stick Insect (Carausius morosus) is one of the most accessible and fascinating phasmids maintained in captivity.
Successful husbandry requires a tall, well-ventilated enclosure, abundant safe climbing surfaces, appropriate warmth and humidity, and a continuous supply of fresh pesticide-free foliage such as bramble, privet, ivy or other accepted food plants.
Vertical space is critical because stick insects must hang freely while moulting. Insufficient height or physical obstruction can result in severe deformity or death.
Indian Stick Insects are generally calm and can tolerate occasional gentle handling, but their legs are delicate and they should never be pulled from a surface.
Their reproductive biology deserves particular attention. Captive females reproduce primarily through parthenogenesis, meaning no male is required. A single adult female can lay large numbers of viable eggs and potentially establish an entire colony.
Egg management is therefore a fundamental part of responsible husbandry.
With appropriate enclosure design, safe food plants and sensible population control, Carausius morosus is an excellent introductory stick insect and provides an exceptional opportunity to observe camouflage, moulting, regeneration and parthenogenetic reproduction.
IMPORTANT INFORMATION
This care sheet provides general husbandry guidance and does not replace current species-specific research or applicable wildlife, agricultural and import legislation.
Food plants must be correctly identified and free from pesticides, herbicides and other harmful chemical treatments. Washing foliage does not make systemically treated plants safe.
Always provide sufficient unobstructed vertical space for moulting and never disturb an insect actively shedding its exoskeleton.
Females can reproduce without males through parthenogenesis and may produce hundreds of viable eggs. Responsible egg and population management is essential.
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.
