Indian Stick Insect (Carausius morosus)

Carausius morosus

The Carausius morosus, or Indian Stick Insect. It is the 'laboratory' and primary school phasmid par excellence: the most widespread species in the world in captivity since the 19th century. Morphologically similar to the Medauroidea (it is a thread-like green-brown twig), it is distinguished by two bright 'red patches' at the root of the front legs (in adult specimens). It is a creature of astounding biological resilience: it feeds on Ivy and Bramble at a frantic pace, and is famous for being 99.9% parthenogenetic. A single female specimen will give rise, laying hundreds of very hard ovoid eggs, to a self-sufficient colony identical in all respects to the mother. Very docile, nocturnal and very easy to maintain even in the winter months (thanks to the ivy).
