Cockroaches are insects of the order Blattodea (the name Blattaria is often used, but it is not interchangeable "Blattaria" includes a number of extinct taxa which do not belong in the cockroaches, so, in technical terms, Blattaria is a polyphyletic group, and the name Blattodea is therefore preferred). The names of the order are derived from Greek blatta, meaning "cockroach". There are roughly 3,500 species in 6 families. Cockroaches exist worldwide, with the exception of the polar regions and in elevations above 2,000 m (6,500 ft).
The English word cockroach is derived from the Spanish cucaracha, meaning "chafer, beetle".
Among the most well-known species are the American cockroach, Periplaneta americana, which is about 3 cm long, and the German cockroach, Blattella germanica, about 1½ cm long. Tropical cockroaches are often much bigger, and in turn prehistoric forms such as the Carboniferous Archimylacris and the Permian Apthoroblattina were several times as large as these. When infesting buildings, cockroaches are considered pests; out of the thousands of species, however, only a handful fall into this designation.
