Deroplatys desiccata
The dead leaf mantis — extraordinary camouflage in a large, shield-bodied package.
About Deroplatys desiccata
Deroplatys desiccata is a large mantis from the tropical forests of Malaysia and Southeast Asia. Its camouflage is among the most impressive in the insect world — the entire body, including a broad, shield-like prothoracic extension, resembles a dried, crumpled leaf. Colouration ranges from grey-brown to dark reddish-brown, with veining and mottling that mimic leaf damage.
Like all mantids, D. desiccata undergoes incomplete metamorphosis. Nymphs hatch from an ootheca and develop through successive moults. Adults reach 7–9 cm, with females being stockier and larger than males. Females are typically flightless; males have functional wings.
This species is rated intermediate because it requires slightly more precise humidity management than the standard beginner mantids and can be a more cautious feeder.
Enclosure
Height is non-negotiable. Mantids hang upside-down to moult, and the enclosure must provide at least three times the body length in vertical space — 27 cm minimum for adults. The ceiling must be mesh or textured. Smooth ceilings cause fatal moult failures.
- A tall, well-ventilated terrarium or mesh cage is ideal
- Include branches, dried leaves, and bark to complement the mantis's camouflage and provide perching sites
- A substrate of coco coir or leaf litter helps maintain humidity at the base
- House individually — cannibalism in mantids is predatory behaviour, not a sign of inadequate feeding
Temperature & humidity
Keep at 22–28°C during the day. A small heat mat on the side of the enclosure is useful in cooler months. Avoid excessive heat — this species comes from shaded forest floor environments, not exposed canopy.
Humidity should be maintained at 60–75%. Mist lightly once daily. The substrate layer helps buffer humidity between mistings. Good ventilation is important — D. desiccata is susceptible to mould-related problems in stagnant, overly wet enclosures.
Feeding
D. desiccata is a classic ambush predator. It will sit motionless among leaves, waiting for prey to walk past. It can be a more hesitant feeder than assertive species like Sphodromantis, so patience is sometimes needed. Offer live prey only, sized to fit the raptorial forelegs.
- Small nymphs: fruit flies
- Medium nymphs: houseflies, small crickets
- Adults: locusts, crickets, bluebottle flies, cockroaches
Feed every 2–3 days. If the mantis ignores prey, try a different type — some individuals have strong preferences. Do not overfeed; a swollen abdomen increases moult failure risk.
Behaviour
When disturbed, D. desiccata has two defensive strategies. It may freeze and flatten against a surface, relying on its leaf camouflage. Alternatively, it can perform a threat display — raising its forelegs and flashing the inner surfaces of the prothoracic shield to reveal darker, contrasting markings. This display is a bluff, and the species is not aggressive toward keepers.
Handling is possible with care, but these mantids prefer to remain still and undisturbed. They are a species best appreciated by watching rather than holding.
