hey mate here is your answer..

Cockroaches are insects of the order Blattodea, which also includes termites. About 30 cockroach species out of 4,600 are associated with human habitats. About four species are well known as pests.

The cockroaches are an ancient group, dating back at least as far as the Carboniferousperiod, some 320 million years ago. Those early ancestors however lacked the internal ovipositors of modern roaches. Cockroaches are somewhat generalized insects without special adaptations like the sucking mouthparts of aphids and other true bugs; they have chewing mouthparts and are likely among the most primitive of living neopteraninsects. They are common and hardy insects, and can tolerate a wide range of environments from Arctic cold to tropicalheat. Tropical cockroaches are often much bigger than temperate species, and, contrary to popular belief, extinct cockroach relativesand 'roachoids' such as the Carboniferous Archimylacris and the Permian Apthoroblattinawere not as large as the biggest modern species.
