Do females stick insects need a male to lay eggs?

Some stick insect species do have the males and females sexes, but other species do not. It really depends on the exact species as to how they reproduce.

For example, the best known stick insects are the Indian Stick Insect (also known as the Laboratory Stick Insect). These can grow to around 10cm (4 inches). They are known to reproduce parthenogenically, a Word that means an unfertilized egg is capable of hatching into a new individual. Males of this species are unrecorded, although gynandromorphs are quite common. Gynandromorph meaning having both male and female parts.
