DESCRIPTION

Cockroaches are dorsoventrally compressed (flattened). Forewings (tegmina) are tough, and leathery. The first dorsal thoracic segment (pronotum) covers the head. Antennae are threadlike (filiform). The basal leg segments (coxae) are elongate, and quite large, making the insect well-adapted for a running (cursorial) lifestyle. Cerci (appendages at posterior of abdomen) are multi-segmented.
