Heteropteryx dilatata
A giant stick insect of the Malay Archipelago. Females reach 14-17cm and 30-65g, among the heaviest of living insects. They are lime green and thorny, and their shortened wings will not carry them.
Heteropteryx dilatata is a giant stick insect of the Malay Archipelago and the only species in its genus, which gives its name to the family Heteropterygidae. It is recorded from the Malay Peninsula, Thailand, Singapore, Sumatra and Sarawak on Borneo, and is nocturnal. Females are far larger and broader than males, reaching 14-17cm and 30-65g, which puts them among the heaviest insects alive. They are usually lime green, though yellow and, more rarely, red-brown individuals occur. Both pairs of wings are shortened, the green forewings covering strikingly pink hindwings at rest, and the insect cannot fly. Head, body and legs are thorny, and a secondary ovipositor sits at the end of the abdomen. Males are much smaller and slender at 9-13cm, spined all over, mottled brown, with hindwings that cover the whole abdomen. Both sexes stridulate in defence, jerking the wings open again and again, and threaten with the abdomen raised and the spiny hind legs splayed, snapping them shut like scissors on contact.

It comes from tropical forest in the Malay Archipelago, so mist the enclosure against drying. Females are 14-17cm and heavy, so moulting needs real height and footholds strong enough to bear the weight.
The female lays into the ground using the secondary ovipositor at the end of the abdomen. Phasmid eggs resemble plant seeds, and in captivity they wait to hatch within the substrate.
It is placid, and several of the same species can share an enclosure. Being touched during a moult easily spoils it, so give the container height and plenty of footholds. When alarmed it snaps the hind legs shut like scissors and defends itself with the spines on the tibiae, so handle it with care.
Across stick insects as a whole, lifespans run from a few months to at most three years. Being a large species, it also takes longer to reach maturity.
The import of insects, foreign stick insects included, is regulated under Japan's Plant Protection Act, and whether a given species may enter depends on the country it comes from. What circulates in Japan is captive-bred stock, so buy from a clear source and never let one loose outdoors. The eggs look like plant seeds, so always check the substrate for them before discarding it.
