Field Cockroach – Blatella Vega
This roach is very similar in appearance to the German and Asian cockroaches but can be distinguished from these by a dark area located on the face between the base of the mouthparts and the eyes. This species is also slightly smaller and more greenish-brown or silver tinted in color than the German roach. As with the
German and Asian roaches there are 2 black parallel bars running the length of the pronotum (top of the prothorax)
The field (vaga) roach was introduced from Asia into California, Arizona, New Mexico and Texas. Unlike the German roach, the Field (Vaga) cockroach normally lives outdoors where it feeds on decaying vegetation. This species is not repelled by light and is often active during the daytime. Although primarily a field insect, in many cases it is actually attracted to lights on buildings or streetlights and then enters the structure through cracks and crevices during dryer months in search of water.
