Giant Asian Mantis

Hierodula membranacea — the giant Asian mantis — is one of the largest mantises in Southeast Asia and one of about 80 species in genus Hierodula (the giant mantises of tropical Asia). The species is widespread across South and Southeast Asia (India, Sri Lanka, Bangladesh, Myanmar, Thailand, Vietnam, Indonesia, Philippines, southern China). Adults are 8-10 cm body length, with females substantially larger than males (males 6-7 cm). The species is sexually dimorphic with females larger and more robust than males. Body coloration is typically bright leaf-green (the typical Hierodula tropical-foliage camouflage), occasionally yellow-green or brown variants. The species' major significance comes from PREDATION ON VERTEBRATE PREY. Giant Asian mantis females are voracious predators capable of capturing very large prey items — including SMALL LIZARDS (anoles, geckos, small skinks), SMALL SNAKES (juvenile snakes up to 15-20 cm long), HUMMINGBIRDS (rare but documented predation events on small hummingbirds visiting flowers — especially in regions where Hierodula species and small hummingbirds co-occur), and other small vertebrates. The species is one of the most-cited examples of mantis predation on vertebrate prey and is featured in essentially every modern textbook discussion of arthropod predation on small vertebrates. The species is also one of the most popular MANTIS PET SPECIES worldwide. Captive breeding programs have made the species widely available in the global insect-pet trade — popular among insect keepers because of the dramatic size, attractive bright green coloration, and relatively easy captive husbandry. The species is one of the most-photographed and most-Instagrammed pet mantises in modern social media. Wild populations face habitat-loss pressure from tropical forest clearing in Southeast Asia. The species is harmless to humans (no venom, no significant bite — though large females can deliver a sharp pinch from the raptorial front legs if forcibly handled) and is a flagship species of Southeast Asian arthropod biology.
