Cockroaches. Anatomy and habits

 Like most other insects, cockroaches have an exoskeleton, meaning their skeleton is located on the outside of their bodies. They have three simple body parts: the head, thorax, and abdomen. Their head is dominated by their long antennae that are constantly moving and sensing the environment. 

German cockroach

The German cockroach is the cockroach of concern, the species that gives all other cockroaches a bad name. It occurs in structures throughout Florida, and is the species that typically plagues multifamily dwellings. In Florida, the German cockroach may be confused with the Asian cockroach, Blattella asahinai Mizukubo. While these cockroaches are very similar, there are some differences that a practiced eye can discern.
