They are | The life cycle of the Madagascar hissing cockroach is a little different then the life cycles of other cockroaches. They are ovoviviparous, meaning they give birth to live young. This unique insect displays incomplete metamorphosis (egg, nymph, adult.)<ref name=UK-entomology/> The adult male uses its hissing sound as a courtship call for the female. The male with also defend his mating grounds with hissing and pushing and shoving the other males. The hissing cockroach can breed all year round but they usually do it when the weather is warm. The female produces a special scent that the male cockroach is attracted to. They detect the scent with their antennae. This scent decreases with age. | ||
When the two cockroaches find each other, they begin by touching each other's antennae. Next they put their rears together for about thirty minutes (internal fertilization).<ref name=Animal-Diversity-web/> The female cockroach has an internal egg sac called the ootheca. The female carries the eggs inside for about two months. When the eggs hatch, they are released. About fifteen to forty cockroach nymphs (look like mini adults but lack reproductive organs) will come out.<ref>Sreng, L.

The Madagascar hissing cockroach lives two to five years in the wild and in captivity.<ref name=Animal-Diversity-web/> | |||
