What is a Cockroach?

The cockroach is characterized by a flattened oval body, long hairlike antennae, and a glossy black or brown leathery integument. The head is bent downward, and the mouthparts are directed backward instead of forward or downward as is the case in the majority of other insects. The male generally has two pairs of wings, but the female, who in some species, is wingless or holds vestigial wings. The female produces eggs in egg cases (labeled oothecae). These are on occasion held away from her body or may be held in protected areas. After the female deposits an egg case, the soft, white nymphs emerge. As their exoskeleton hardens, it turns brown in appearance. The structure and big size (some species demonstrate a wingspread measurement of higher than 12 cm [4.7 inches]) of cockroaches have become a particular interest in the biological laboratory.
The cockroach likes a warm, humid, dark living and is frequently thriving in tropical or other mild locations. Just a couple species have become pests. The insect harms more material than it digests and possesses a disagreeable smell. The eating habits of the roach, which includes both plant and animal product, ranges from food, paper, clothing, and books to dead insects, particularly bedbugs. Insecticides are taken in roach termination.
The American cockroach (species Periplaneta americana) is 30 to 50 mm long (up to about 2 inches), reddish brown, and lives in an outdoor habitat or in dark, heated indoor spaces (e.g., basements and furnace rooms). During its adult life, generally about 1.5 years, the female deposits 50 or more oothecae, each containing around 16 eggs that hatch after 45 days. Nymphal life lasts from 11 to 14 months. The American cockroach, a native of tropical and subtropical America, possesses well-developed wings. However, most species are unlikely to be good flyers.
The German cockroach (Blattella germanica), a common household pest and is often erroneously labeled a waterbug, is light brown with two dark stripes on the prothoracic region. The female deposits the ootheca three days after mating and carries it for generally about 20 days. Because it is tiny (about 12 mm [less than 0.5 inch] long), this cockroach generally can be carried into houses in grocery bags and boxes; it has been spread across the globe by boat. Three or more generations might breed yearly. This cockroach, found abundantly in the water pipes of the Croton Aqueduct in New York City, is commonly labeled the Croton bug.
The brown-banded cockroach (Supella supellectilium) resembles the German cockroach but is a little bit smaller. The male possesses totally developed wings and is paler in hue than the female, whose wings are stunted and nonfunctional. Both sexes have two light-coloured bands over the back. The adult life span is around 200 days, and there might be two generations a year. Eggs are be left in clothes, wood molding, or cracks in the floor. With the innovation of heated buildings this cockroach became common in cooler areas.
The Oriental cockroach (Blatta orientalis) is thought to be one of the dirtiest of household pests. It is oval, shiny black or dark brown, 25 to 30 mm (1 to 1.2 inches) long, with a life cycle resembling that of the American cockroach. The male has short, fully developed wings, and the female has vestigial wings. This cockroach has been spread in vehicles of trade from its Asiatic origins to almost all the temperate regions.
Wood roaches are non-domestic pests. Parcoblatta pennsylvanica, the common wood cockroach, lives under logs and stones in northern latitudes. The male and female are so different in appearance that they were once thought to be unique species. The male, 15 to 25 mm (0.6 to 1 inch) long, possesses wings that extend past the abdomen; the female is smaller and possesses much shorter wings. Cryptocercus punctulatus digests wood with the assistance of certain protozoans in its digestive tract.
