Devil’s Flower Mantis (Idolomantis diabolica) Care Sheet
The Devil’s Flower Mantis (Idolomantis diabolica) is one of the largest, most spectacular and most sought-after flower mantises in captivity. Its extraordinary combination of leaf-like lobes, elaborate body shape and dramatic defensive display makes it instantly recognisable.
Native to East Africa, this species is considerably more demanding than many commonly kept mantises. It requires careful control of temperature, ventilation, hydration, live-food availability and moulting space, and mistakes during the nymphal stages can result in serious moulting problems.
For this reason, the Devil’s Flower Mantis is best regarded as an:
advanced-level mantis species.
One of the most important aspects of its husbandry is ventilation. Although the species requires appropriate hydration, it should not be maintained in a stagnant, permanently saturated enclosure. Warm conditions combined with strong airflow and access to drinking droplets are generally preferable.
Another major consideration is feeding. Idolomantis diabolica is particularly well adapted to capturing flying insects, and flies should form an important part of the captive diet.
Successful husbandry centres around a tall, spacious and exceptionally well-ventilated enclosure, warm temperatures, appropriate hydration, abundant flying prey and generous unobstructed space for moulting.

Natural Distribution
Idolomantis diabolica originates from:
East Africa.
Its natural range includes areas of countries such as:
- Tanzania
- Kenya
- Uganda
- Ethiopia
- Somalia
The species occurs in warm environments containing shrubs and flowering vegetation where flying insects provide abundant prey.
Natural Lifestyle
Devil’s Flower Mantises are:
ambush predators.
They spend long periods positioned among vegetation waiting for insects to approach.
Their elaborate appearance serves both:
- Camouflage
- Defensive display
When prey comes within range, the mantis captures it using powerful raptorial forelegs.
Appearance
The Devil’s Flower Mantis possesses an extraordinary body structure.
Characteristic features include:
- Large body size
- Broad leaf-like leg lobes
- Elaborate thoracic structures
- Long antennae
- Powerful raptorial forelegs
- Large wings in adults
- Complex green, cream, brown and reddish colouration
At rest, the insect can blend remarkably well with vegetation.
Why Is It Called the Devil’s Flower Mantis?
The common name comes from the combination of its:
flower-like appearance and dramatic defensive display.
When threatened, the mantis can suddenly expose brightly coloured inner surfaces that contrast dramatically with its normal resting appearance.
Defensive Display
The threat display of Idolomantis diabolica is one of the most spectacular among mantises.
A threatened individual may:
- Raise its body
- Spread the raptorial forelegs
- Open the wings
- Expose contrasting colours
- Turn toward the perceived threat
This makes the insect suddenly appear much larger.
Do Not Provoke Displays
Defensive displays should be observed naturally rather than deliberately triggered.
Repeatedly frightening an animal for photographs or entertainment creates unnecessary stress.
If a mantis adopts a defensive posture:
stop disturbing it and allow it to settle.
Adult Size
The Devil’s Flower Mantis is a large species.
Adult females commonly reach approximately:
11–13 cm.
Adult males are generally somewhat smaller and more slender, often around:
10–11 cm.
Their long legs and elaborate body structures make them appear even larger.
Sexual Dimorphism
Adult males and females differ considerably.
Females are generally:
- Larger
- Broader
- Heavier
- More robust
Males are:
- Slimmer
- Lighter
- More mobile
- Better fliers
Sexing becomes increasingly straightforward as the animals mature.
Antennae
Adult males develop conspicuous:
feathery antennae.
These are substantially more elaborate than the antennae of adult females.
The male antennae help detect chemical signals associated with receptive females.
Adult Females
Adult females are particularly impressive.
They possess:
- Large abdomen
- Broad body
- Elaborate lobes
- Powerful forelegs
- Fully developed wings
Their substantial body weight makes them less agile in flight than males.
Adult Males
Adult males are:
- More slender
- More active
- Equipped with feathery antennae
- Capable of effective flight
Additional escape precautions are essential once males become adult.
Flight
Adult males can fly very well.
Females also possess functional wings, although their greater body mass makes them less agile.
Always perform enclosure maintenance:
- Indoors
- Away from open windows
- Away from exterior doors
- In a secure room
Raptorial Forelegs
The front legs are modified into powerful prey-catching structures called:
raptorial forelegs.
These remain folded while the mantis waits.
When prey approaches, the forelegs strike rapidly and secure the insect using spines.
Diet
Devil’s Flower Mantises require:
live insect prey.
Flying insects are particularly important.
Suitable feeders include:
- Fruit flies for small nymphs
- House flies
- Green bottle flies
- Blue bottle flies
- Other appropriately sized captive-bred flies
- Suitable moths from safe captive cultures
Flying Prey
Flies should form a major component of the diet.
The species is particularly well adapted to capturing:
flying insects.
Flies encourage natural hunting behaviour and tend to move through the upper parts of the enclosure where the mantis spends much of its time.
Fruit Flies
Young nymphs can begin with:
- Drosophila melanogaster
- Drosophila hydei
The appropriate species depends upon the size of the nymph.
Larger Flies
As the mantis grows, transition onto larger prey such as:
- House flies
- Green bottle flies
- Blue bottle flies
Maintaining reliable fly cultures or pupae is therefore an important part of keeping this species.
Crickets
Crickets are generally less suitable as a principal food for Devil’s Flower Mantises.
They are:
- Ground oriented
- Capable of hiding
- Capable of biting
- Potentially dangerous during moulting
If used at all, they should be offered cautiously and removed if uneaten.
Locusts
Although some large mantises readily accept locusts, Idolomantis diabolica is particularly adapted to flying prey.
Locusts should not automatically replace flies as the main diet.
Roaches
Roaches may occasionally be accepted, but many species immediately hide low in the enclosure.
Flying feeders generally produce a stronger feeding response.
Wild-Caught Prey
Wild insects should generally be avoided.
Potential risks include:
- Pesticides
- Parasites
- Pathogens
- Unknown chemical exposure
Purpose-bred feeders are considerably safer.
Feeding Frequency
Feeding frequency depends upon:
- Developmental stage
- Temperature
- Prey size
- Abdomen condition
- Reproductive status
Young growing nymphs generally require frequent access to prey.
Adults can usually consume larger meals less frequently.
Abdomen Condition
Observe the abdomen.
A thin abdomen may indicate that feeding is appropriate.
A very full abdomen suggests additional food is unnecessary immediately.
Avoid attempting to keep the animal constantly overfed.
Feeding Before a Moult
A nymph approaching a moult often stops feeding.
If this occurs:
- Remove uneaten prey
- Maintain appropriate hydration
- Avoid handling
- Avoid enclosure disturbance
Do not attempt to force-feed a premoult mantis.
Housing
The Devil’s Flower Mantis requires:
a tall, spacious and extremely well-ventilated enclosure.
Suitable options include:
- Large mesh mantis cages
- Purpose-built ventilated enclosures
- Tall terrariums with substantial cross-ventilation
Ventilation should never be treated as an afterthought.
Enclosure Size
The species becomes very large.
Adult housing should provide considerably more space than that used for small mantises.
For an adult female, approximately:
30 × 30 × 45 cm or larger
provides a useful starting point.
More space is beneficial provided prey remains accessible.
Moulting Height
This is one of the most important husbandry requirements.
The enclosure should be at least:
three times the mantis’ body length in usable vertical height.
For large females, generous additional clearance is strongly recommended.
Why Moulting Space Is Critical
A mantis moults while suspended upside down.
The animal must:
- Grip securely above the ground.
- Hang completely free.
- Split the old exoskeleton.
- Pull downward from it.
- Extract the legs and raptorial forelegs.
- Extend the body fully.
- Remain hanging while the new exoskeleton hardens.
A large Idolomantis needs substantial clearance.
Final Moult
The final moult is particularly demanding.
During this moult the adult must expand:
- Body
- Legs
- Forelegs
- Large wings
An obstruction can result in permanent deformity.
Clear Moulting Zone
Keep substantial space beneath the enclosure roof free from:
- Dense plants
- Branches
- Decorations
- Feeding containers
A large mantis needs room to emerge without touching anything.
Roof Grip
The roof must provide excellent grip.
Suitable materials include:
- Fine plastic mesh
- Fabric insect mesh
- Other safe textured surfaces
Smooth glass or acrylic alone is unsuitable as the primary moulting surface.
Metal Mesh
Avoid sharp or coarse metal mesh.
Mantises can damage their delicate feet on unsuitable mesh.
Use smooth insect-safe materials.
Ventilation
Excellent airflow is essential.
Devil’s Flower Mantises are particularly vulnerable to husbandry that combines:
high moisture with poor ventilation.
The enclosure should never become stagnant.
Mesh Enclosures
Mesh enclosures are particularly useful because they provide:
- Strong airflow
- Excellent climbing surfaces
- Numerous moulting positions
However, they lose humidity rapidly.
Hydration must therefore be provided deliberately.
Cross-Ventilation
If using a solid-sided enclosure, provide substantial:
cross-ventilation.
Air should be able to move through the enclosure rather than simply escaping through a few holes in the roof.
Temperature
The Devil’s Flower Mantis requires warmer conditions than many beginner mantises.
A useful daytime range is approximately:
26–32°C.
Nighttime temperatures can fall somewhat lower.
Ideal Daytime Temperature
Approximately:
28–30°C
provides a useful general target for established nymphs and adults.
Avoid uncontrolled overheating.
Night Temperature
A moderate nighttime reduction is natural.
Temperatures around:
20–24°C
can generally be appropriate at night.
Avoid prolonged cold conditions.
Heating
In many homes supplemental heating will be required.
Suitable approaches include:
- Heating the room
- External heat sources
- Controlled radiant heat
Any dedicated heating equipment should be regulated.
Thermostat
Use:
a reliable thermostat
with dedicated heat sources.
Small enclosures can overheat very quickly.
Temperature Monitoring
Use an accurate thermometer positioned appropriately within the enclosure environment.
Do not rely upon:
- Guesswork
- Room thermostat alone
- Touching the enclosure
The temperature experienced by the mantis can differ from general room temperature.
Direct Sunlight
Never use direct sunlight as a heat source.
A transparent enclosure positioned in sunlight can reach lethal temperatures extremely quickly.
Humidity
Humidity requirements are sometimes misunderstood with this species.
Devil’s Flower Mantises require appropriate hydration, particularly for successful moulting, but this does not mean keeping them in permanently saturated conditions.
A practical approach is:
moderate humidity combined with exceptional ventilation and regular drinking opportunities.
Humidity Range
Approximately:
40–60% relative humidity
may be suitable through much of routine maintenance, with temporary increases following misting.
Exact requirements vary with:
- Temperature
- Ventilation
- Developmental stage
- Local climate
Successful hydration should be assessed alongside actual enclosure conditions rather than relying solely on a hygrometer number.
Hydration
Hydration is extremely important.
Provide drinking opportunities through:
regular light misting.
The mantis should be able to drink droplets from enclosure surfaces.
Misting
Light misting can be carried out regularly depending upon enclosure drying rate.
In a highly ventilated warm enclosure, surfaces may dry rapidly.
The objective is to provide:
- Drinking droplets
- Temporary humidity
without producing permanently damp conditions.
Drinking Behaviour
A thirsty mantis may actively drink droplets from:
- Mesh
- Leaves
- Branches
- Enclosure walls
Observe the animal during and after misting.
Direct Spraying
Avoid forcefully spraying the mantis.
Use a fine mist directed primarily toward nearby surfaces.
Humidity and Moulting
Poor hydration can contribute to moulting difficulties.
However, simply saturating the enclosure is not the solution.
Correct husbandry requires:
hydration + ventilation + adequate moulting space.
All three are important.
Substrate
Simple substrate is suitable.
Options include:
- Paper towel
- Plain paper
- Thin absorbent substrate
- Naturalistic substrate
Paper makes routine maintenance particularly straightforward.
Furnishings
Useful furnishings include:
- Thin branches
- Safe artificial foliage
- Pesticide-free live plants
- Mesh climbing surfaces
Do not overcrowd the enclosure.
Branch Positioning
Provide branches at several angles while preserving open space beneath the roof.
The mantis should be able to:
- Climb
- Rest
- Hunt
- Select moulting positions
without obstruction.
Lighting
Provide a clear day/night cycle.
The species is primarily visually oriented and active during daylight.
Approximately:
12 hours light and 12 hours dark
provides a practical general cycle.
Bright Lighting
Good daytime illumination can encourage normal activity.
Lighting must not create dangerous heat.
Monitor enclosure temperature whenever additional lights are installed.
UVB
Specialised UVB lighting is not generally considered essential for routine husbandry.
If lighting is used, its most important roles are:
- Establishing a day/night cycle
- Supporting live plants where present
- Providing appropriate visible illumination
Handling
Handling should remain:
limited.
These are large but delicate insects.
If handling is necessary:
- Allow the mantis to step onto your hand
- Move slowly
- Keep it away from your face
- Remain close to a safe surface
- Avoid touching the abdomen or wings
Never Grab a Mantis
Do not restrain the mantis by:
- Legs
- Abdomen
- Thorax
- Wings
Allow it to move voluntarily whenever possible.
Handling Adult Males
Adult males are capable fliers.
Never handle them:
- Outdoors
- Beside open windows
- Near exterior doors
They can take flight suddenly.
Raptorial Strikes
A large mantis can strike defensively with its raptorial forelegs.
This may be uncomfortable.
The species is:
not venomous.
Respect defensive behaviour and avoid provoking the animal.
Moulting
Moulting is one of the greatest challenges in keeping Idolomantis diabolica.
Correct moulting conditions should be considered from the moment the enclosure is designed.
Premoult Signs
Signs may include:
- Refusal of food
- Reduced activity
- Prolonged upside-down hanging
- Changes in body proportions
- Avoidance of prey
Remove live feeders when premoult is suspected.
During a Moult
Never:
- Handle the mantis
- Shake or move the enclosure
- Spray directly onto the animal
- Introduce prey
- Touch the exuvia
A fall during moulting can be fatal.
Freshly Moulted Mantises
Immediately after moulting, the new exoskeleton is soft.
The mantis may appear:
- Pale
- Weak
- Unusually stretched
This is normal.
Allow it to harden undisturbed.
Feeding After Moulting
Do not offer large or aggressive prey immediately after a moult.
Wait until the mantis:
- Has hardened
- Is gripping normally
- Shows normal coordination
before resuming feeding.
Exuvia
The discarded exoskeleton is called the:
exuvia.
It can normally be removed after the mantis has completely finished moulting and moved away.
Mismoults
Mismoults are among the most serious problems encountered with this species.
Possible contributing factors include:
- Inadequate height
- Poor roof grip
- Dehydration
- Inappropriate humidity
- Physical obstruction
- Disturbance
- Falls
Prevention is far more effective than attempting to correct a severe mismoult afterwards.
Wing Problems
Problems during the final moult may result in:
- Crumpled wings
- Bent wings
- Incomplete expansion
Once hardened, severely deformed adult wings cannot be corrected through another moult.
Nymph Housing
Young nymphs require appropriately sized enclosures.
Housing should provide:
- Fine ventilation
- Secure roof grip
- Warmth
- Drinking droplets
- Tiny flying prey
- Sufficient moulting clearance
Increase enclosure size as the nymph grows.
Hatchling Food
Small nymphs can begin on:
fruit flies.
As they grow, gradually transition onto larger flying prey.
Nymph Growth
The species passes through multiple nymphal instars before adulthood.
Development speed depends upon:
- Temperature
- Feeding
- Sex
- Individual genetics
Females generally require more development than males.
Sexing
Sex becomes increasingly apparent as the mantises mature.
Adult males are particularly distinctive because of their:
large feathery antennae.
Females become much broader and heavier.
Male Development
Males commonly mature earlier than females.
This creates a challenge for breeders because males may age before females become ready to mate.
Managing Development Rates
Experienced breeders may attempt to synchronise development by:
- Keeping males slightly cooler
- Feeding males less heavily
- Keeping females appropriately warm
- Feeding females more consistently
Any manipulation must remain within safe husbandry limits.
Never deliberately starve or dangerously chill an animal.
Social Housing
Young Idolomantis are sometimes maintained communally by experienced breeders under carefully controlled conditions.
However:
cannibalism remains possible.
For general pet husbandry, individual housing provides the greatest control and lowest risk.
Adult Housing
Adults should generally be housed individually.
This allows the keeper to monitor:
- Feeding
- Hydration
- Moulting
- Reproductive condition
and eliminates routine cannibalism risk.
Breeding
Breeding Devil’s Flower Mantises is:
advanced.
Success depends upon:
- Correctly timed adults
- Mature male
- Mature female
- Excellent female condition
- Careful introduction
- Suitable breeding space
Female Maturity
Do not introduce a male immediately after the female’s final moult.
Allow the female time to:
- Harden completely
- Feed extensively
- Reach reproductive maturity
Male Maturity
The male also requires time after reaching adulthood.
A newly moulted adult should not be used immediately for breeding.
Preparing the Female
The female should be:
well fed before introduction.
This may reduce, but does not eliminate, the risk of sexual cannibalism.
Introducing the Male
Allow the male to approach:
from behind.
Never place him directly in front of a hungry female.
Provide sufficient room for escape.
Courtship
Male behaviour may include:
- Careful observation
- Slow approach
- Short flights
- Jumping onto the female
Avoid unnecessary interference once courtship begins.
Sexual Cannibalism
Females can attack and consume males.
Cannibalism may occur:
- Before mating
- During mating
- After mating
Breeding attempts require close supervision.
After Mating
Once mating has concluded and the male has separated, remove him when it is safe to do so.
Do not permanently house a breeding pair together.
Ootheca
Females produce protective egg cases called:
oothecae.
Each ootheca contains multiple eggs.
Ootheca Attachment
Oothecae may be attached to:
- Branches
- Mesh
- Enclosure walls
- Other firm surfaces
Avoid pulling a firmly attached ootheca from its surface unnecessarily.
Ootheca Incubation
Oothecae require:
- Warmth
- Good ventilation
- Appropriate hydration
They should not remain constantly wet.
Incubation Temperature
Approximately:
25–30°C
provides a useful general incubation range.
Avoid extreme temperatures.
Incubation Humidity
Moderate humidity with good airflow is appropriate.
Light periodic misting can prevent excessive drying.
Do not soak the ootheca.
Hatching
Incubation commonly takes:
several weeks to a few months
depending upon environmental conditions.
Do not discard a healthy-looking ootheca simply because an expected date has passed.
Preparing for Hatchlings
Before hatching, prepare:
- Numerous rearing containers
- Established fruit fly cultures
- Appropriate heating
- Fine ventilation
- Safe moulting surfaces
Do not wait until nymphs emerge before arranging food.
Hatchlings
Newly hatched nymphs require immediate access to tiny live prey.
Fruit flies are usually the most practical first feeder.
Maintain:
- Warmth
- Hydration
- Ventilation
- Moulting space
from the beginning.
Cannibalism Among Nymphs
Young nymphs may sometimes tolerate one another better than adults, but cannibalism can still occur.
Risk increases with:
- Hunger
- Size differences
- Overcrowding
- Moulting
Separate animals where practical.
Population Planning
Breeding Idolomantis diabolica can produce substantial numbers of nymphs.
Before breeding, ensure you can provide:
- Enough enclosures
- Enough flying prey
- Appropriate heating
- Daily maintenance
- Responsible homes for surplus animals
Health
Most captive problems arise from husbandry errors.
Major risks include:
- Mismoults
- Dehydration
- Overheating
- Poor ventilation
- Excessive moisture
- Inadequate prey
- Falls
- Pesticide exposure
Warning Signs
Potential concerns include:
- Repeated falling
- Poor grip
- Loss of coordination
- Severe limb deformity
- Failed moulting
- Persistent weakness
- Prolonged refusal of food unrelated to premoult
Pesticide Exposure
Never offer feeders that may have contacted pesticides.
Possible signs of poisoning include:
- Trembling
- Loss of coordination
- Falling
- Inability to grip
- Rapid deterioration
There is little effective treatment for severe pesticide poisoning.
Prevention is essential.
Cleaning
Routine maintenance should include:
- Removing dead feeders
- Removing prey remains
- Removing excessive droppings
- Replacing dirty substrate
- Removing mould
Avoid major enclosure disturbance when a moult is approaching.
Household Chemicals
Keep the enclosure away from:
- Fly sprays
- Flea treatments
- Ant killer
- Insecticides
- Garden pesticides
Remember:
a mantis is an insect.
Products designed to kill household insects can also kill captive mantises.
Aerosols
Avoid spraying near the enclosure:
- Air fresheners
- Cleaning products
- Perfume
- Deodorising sprays
Excellent enclosure ventilation means airborne chemicals can enter very easily.
Quarantine
New mantises should be maintained separately.
Monitor:
- Feeding
- Coordination
- Hydration
- Moulting
- General condition
before positioning them close to an established collection.
Captive-Bred Animals
Captive-bred specimens should be strongly preferred.
Advantages include:
- Known origin
- Known developmental stage
- Established captive feeding
- Reduced pressure on wild populations
Responsible Sourcing
Before obtaining a Devil’s Flower Mantis, ask:
- Is it captive-bred?
- What instar is it?
- When did it last moult?
- What prey is it currently eating?
- Has it been sexed?
Knowing the current feeding regime is particularly useful.
Legal Considerations
Regulations concerning exotic mantises vary by jurisdiction.
Restrictions may apply to:
- Possession
- Breeding
- Sale
- Transport
- Import
- Export
Always verify current regulations before obtaining or distributing animals.
Never Release Captive Mantises
Never release:
- Adults
- Nymphs
- Oothecae
into the environment.
Non-native predatory insects may create ecological risks.
Common Husbandry Mistakes
Common mistakes include:
- Keeping the enclosure too cool
- Poor ventilation
- Excessively high humidity
- Inadequate hydration
- Insufficient moulting height
- Poor roof grip
- Feeding an inappropriate diet dominated by ground prey
- Failing to maintain a reliable supply of flies
- Leaving dangerous feeders with a premoult mantis
- Handling during moulting
- Overheating
- Direct sunlight
- Breeding without preparing for hatchlings
- Underestimating adult male flight
Are Devil’s Flower Mantises Suitable for Beginners?
Generally:
No.
This species is better suited to experienced mantis keepers.
The principal challenges include:
- High temperature requirements
- Strong ventilation requirements
- Hydration management
- Dependence on suitable flying prey
- Large enclosure requirements
- Sensitive moulting
- Difficult breeding synchronisation
A keeper gaining experience would generally be better beginning with a more forgiving species such as a Ghost Mantis or another established beginner mantis.
Educational Value
The Devil’s Flower Mantis provides exceptional opportunities to observe:
- Floral and vegetation camouflage
- Ambush predation
- Raptorial hunting
- Dramatic defensive displays
- Sexual dimorphism
- Feathery male antennae
- Moulting
- Wing development
- Courtship
- Ootheca production
Few captive insects demonstrate such a dramatic combination of camouflage and defensive behaviour.
Responsible Ownership
Before obtaining Idolomantis diabolica, ensure you can provide:
- Reliable warm temperatures
- Thermostatically controlled heating where necessary
- Exceptional ventilation
- Regular hydration
- A continuous supply of appropriate flying prey
- Large vertically oriented housing
- Excellent moulting surfaces
- Time for careful observation
This is not an ideal species for a keeper seeking a low-maintenance invertebrate.
Summary
The Devil’s Flower Mantis (Idolomantis diabolica) is one of the largest and most spectacular flower mantises maintained in captivity.
Its elaborate body, leaf-like lobes and dramatic threat display make it an extraordinary display animal, but its husbandry is significantly more demanding than that of many commonly kept mantises.
Successful care requires warm temperatures, exceptional ventilation, regular access to drinking droplets, a diet dominated by appropriately sized flying insects and generous unobstructed moulting space.
A daytime temperature around 26–32°C, with approximately 28–30°C providing a useful general target, is appropriate for established animals. Moderate nighttime cooling can be provided.
Humidity should not be interpreted as a requirement for a permanently wet enclosure. Hydration is essential, but it should be combined with excellent airflow and opportunities for surfaces to dry.
Flies are particularly important feeders. Keepers should establish a reliable source of appropriately sized fruit flies, house flies, green bottle flies or blue bottle flies depending upon the developmental stage of the mantis.
Moulting requires exceptional care. The enclosure must provide secure overhead grip and substantial vertical clearance, particularly during the final moult when the adult wings must expand fully.
Breeding is challenging because males often mature before females, adults can fly and sexual cannibalism is possible. Anyone attempting reproduction should have suitable ootheca incubation facilities, fruit fly cultures and numerous nymph enclosures prepared in advance.
For an experienced keeper able to meet its specialised requirements, Idolomantis diabolica is one of the most remarkable mantises that can be maintained in captivity.
IMPORTANT INFORMATION
This care sheet provides general husbandry guidance and does not replace current species-specific research or applicable wildlife and import legislation.
The Devil’s Flower Mantis is an advanced species requiring careful management of temperature, ventilation, hydration, live prey and moulting conditions.
Provide a tall enclosure with secure overhead grip and substantial unobstructed vertical space. Never disturb or handle an animal while it is moulting or immediately afterwards.
Maintain warm conditions while ensuring exceptional ventilation. Do not confuse appropriate humidity and hydration with keeping the enclosure permanently wet.
A reliable supply of appropriately sized flying prey is essential.
Adult males are capable fliers. Always carry out enclosure maintenance and handling indoors away from open windows and exterior doors.
Never release captive adults, nymphs or oothecae into the environment.
Always verify current regulations concerning possession, breeding, sale, transport, import and export in your jurisdiction.
