Identification and biology:

  • Cockroaches are medium to large sized insects in the order Dictyoptera.
  • They are oval, flat-bodied, dark colored, with chewing mouth parts, three pairs of legs and
    usually two pairs of wings.
  • The cockroach is a Dorso-ventrally flattened insect, meaning it looks flatter when viewed from the side compared to its shape when viewed from above.
  • The head is orientated in a downward-facing position and from above is largely covered by a prominent pronotum (the dorsal surface of first thoracic segment.justbehind the head). Well developed compound eyes and long thread-like antennae are found on the head. The two pairs of wings are differentiated with the tegmina(forewings) being leathery and serving to protect the fan-shaped hind wings, which are the primary flight wings.
  • The wings show mainly longitudinal venation, but are rarely used for flight.
