Blattodea (Cockroaches and Termites)

Blattodea is an order of insects that contains the cockroaches and the termites. Formerly, the termites were considered a separate order, Isoptera, but genetic and molecular evidence suggests an intimate relationship with the cockroaches, both cockroaches and termites having evolved from a common ancestor. The Blattodea and the mantises (order Mantodea) are now all considered part of the superorder Dictyoptera. Blattodea includes approximately 4,400 species of cockroach in almost 500 genera, and about 3,000 species of termite in around 300 genera.
Termites are pale-coloured, soft-bodied eusocial insects that live in colonies whereas cockroaches, are darker-coloured (often brown), sclerotized, segmented insects. Within the colony, termites have a caste system, with a pair of mature reproductives, the king and the queen, and a large number of sterile workers and soldiers. The cockroaches are not colonial but do have a tendency to aggregate and may be considered pre-social, and all adults are capable of breeding. Other similarities between the two groups include various social behaviours, trail following, kin recognition and methods of communication.
