In­dian stick in­sect

This lab favourite doesn’t need love

World of Animals - - Stick Insects -

A fa­mil­iar sight in fam­ily homes, schools and sci­en­tific re­search fa­cil­i­ties, this species is of­ten re­ferred to as the com­mon or lab­o­ra­tory stick in­sect. The cap­tive pop­u­la­tion stems from in­sects col­lected in Tamil Nadu, a state at the south­ern tip of In­dia, but ac­ci­den­tal re­leases have led to the species liv­ing in the wild in many other coun­tries. They’re able to feed on some plants not found in their nat­u­ral range, but these can turn their bod­ies yel­low.

Fe­male In­dian stick in­sects can re­pro­duce partheno­genet­i­cally – with­out males. They lay un­fer­tilised eggs, and these de­velop into lit­tle clones of their moth­ers. Around one in ev­ery 1,000 mem­bers of the species has male gen­i­tals, but these rare in­di­vid­u­als are of­ten ac­tu­ally mas­culinised fe­males that also have fe­male sex­ual or­gans.

Like other in­sects, stick in­sects use a pair of an­ten­nae on their heads to gather information about the world around them.
