They use their wings mainly to control their speed and direction when they drop from the treetops. The females are clumsy flyers, and simply beat their wings to break their fall. The males are much better flyers.
When disturbed, they secrete a foul-smelling substance from their mouthparts. They also frighten off enemies by holding their wings open for several seconds.
These stick insects reproduce by parthenogenesis, meaning that the eggs laid by the female do not need to be fertilized by a male.
