The Giant Rainforest Mantis (Hierodula majuscula) is one of Australia’s largest mantises and is capable of growing to 7cm. Once fully grown the Giant Rainforest Mantis can catch small vertebrates (creatures with backbones) like geckos and Green Tree Frogs (Litoria caerulea).
You can often find them in the tropics in summer and occasionally wandering around back yards.
Tropical forests of Australia around the Queensland region, back yards and where food is plentiful.
As adults, the Giant Rainforest Mantis small vertebrates are occasionally eaten, although their diet mainly consists of butterflies, crickets, grasshoppers, moths, caterpillars etc.
18 months. In captivity, specimens can live nearly 2 years.
The female Giant Rainforest Mantis will produce a foamy froth – also known as an Ootheca. It will harden under the sun, and provide the baby mantids – or nymphs – their first food. The nymphs continue to grow and will shed their skins 6 times before reaching adulthood. Once the males have reached adulthood they will start looking for a mate. Once they find a mate they will cautiously approach and then jump onto her, gripping her thorax. Mating can take approximately 2 hours. After mating has occurred the female Giant Rainforest Mantis will eat the male’s head and dump him, or if he’s lucky he will jump off quickly and run away!
Adult Giant Rainforest Mantis grow to approximately 70mm but some have been recorded to grow to 100mm.
