Most people can recognize cockroaches instantly. They're brown or black insects that are usually between half an inch and two inches long (12-50 millimeters), minus their long antennae. Their heads point downward, almost as if they're built for ramming. Males usually have wings, but females often don't. Those that do usually have vestigial wings -- small, undeveloped wings that often don't allow the roach to fly.
Although their reputation often sets them apart, roaches have a lot in common with other insects. Their bodies have three primary regions -- the head, the thorax and the abdomen. They have three pairs of jointed legs, one pair of antennae and a rigid exoskeleton. Roaches shed their exoskeleton, or molt, several times during their lives. After molting, most roaches are white and easily injured until a hormone called bursicon causes the exoskeleton to darken and harden. Sometimes, a roach can re-grow a lost limb when it molts and even put off molting to allow the new limb to grow.
