One interesting aspect of stick bugs is their ability to reproduce parthenogenetically, a form of asexual reproduction in which unfertilized females produce eggs that all hatch into females. If a male does manage to fertilize an egg, the offspring has a 50-percent chance of emerging as a male.Some stick bug species release their eggs as they move through trees and let them fall to the ground where they become hidden among the ground cover, while other species will drop to the forest floor and lay their eggs one-by-one underground.It can take from six months to a year for these eggs to actually hatch.
