Carausius morosus (the 'common', 'Indian' or 'laboratory' stick insect) is a species of phasmid that is often kept by schools and individuals as pets. Culture stocks originate from an original collection from Tamil Nadu, India. Like the majority of the phasmatodea they are nocturnal. Culture stocks are parthenogenetic females, that can reproduce without mating. There are no reports of males, although in captivity gynandromorphs (female with male characteristics) are sometimes reared.

[edit] Description
Females are elongate and approximately 80-100mm in length. The front legs have red patches at the base of the forelegs, and similar but yellow patches on the mid-legs.
[edit] Behaviour
When disturbed the major defence method is feigning death, the body becoming rigid, and the legs held along the line of the body.
Feeding occurs at night, when the insects are active. During the day they rest (often with legs in line with the body) on their foodplants.
[edit] Care in Captivity
This is an easy species to rear, feeding on fresh privet or ivy (bramble is (unusually) not accepted as readily). They need to be kept in a cage around 25cm in height to allow for successful [moult]ing. Females will lay eggs shortly after reaching adulthood, at the rate of several per night. These can be hatched by keeping them on moist sand or paper towel. Eggs take around months to hatch, depending on many factors including temperature.
[edit] Phasmid Study Group (PSG) Number
This is species number 1 on the Phasmid Study Group Culture List
[edit] Accidental Introductions
Accidental introductions have been recorded around the world, including South Africa, Great Britain and the United States of America. The last has been more problematic than most, with many reports from gardeners of the insects reaching pest proportions, especially in Orange County.
