American cockroach Periplaneta americana


Cockroaches origins extend back at least 300 million years. Fossil evidence suggests that there has been little change to their general body form in this time.


Cockroaches live among decaying leaf matter, under bark, in caves and burrows, on the foliage of shrubs and in the nests of social insects, boring into wood and even adopting a semi aquatic habit.


There are around 3500 species of cockroaches worldwide however only about ten species have exploited the dwellings of humans. Some species have become very successful scavengers that cohabit with people in most communities around the world.
