Of all common cockroach species, the American cockroach has the largest body size; molts 6–14 times(mostly 13 times) before metamorphosis; and has the longest life-cycle, up to approximately 700 days.
It has an average length of around 4 cm (1.6 in) and about 7 mm (0.28 in) tall. Also, they are reddish brown and have a yellowish margin on the pronotum, the body region behind the head. Immature cockroaches resemble adults except they are wingless.
American cockroaches generally live in moist areas, but can survive in dry areas if they have access to water. They prefer warm temperatures and do not tolerate low temperatures. These cockroaches are common in basements, crawl spaces, cracks and crevices of porches, foundations, and walkways adjacent to buildings.
American cockroaches are omnivorous and opportunistic feeders that eat a great variety of materials such as cheese, beer, tea, leather, bakery products, starch in book bindings, manuscripts, glue, hair, flakes of dried skin, dead animals, plant materials, soiled clothing, and glossy paper with starch sizing. They are particularly fond of fermenting foods. They have also been observed to feed upon dead or wounded cockroaches of their own or other species.
The German Cockroach is a small species of roaches, typically about 1.1 to 1.6 cm (0.43 to 0.63 in) long. In colour it varies from tan to almost black, and it has two dark, roughly parallel, streaks on the pronotum running anteroposteriorly from behind the head to the base of the wings.
German cockroach generally reside in human buildings, but is particularly associated with restaurants, food processing facilities, hotels, and institutional establishments such as nursing homes. In cold climates, they occur only near human dwellings, because they cannot survive severe cold.
German cockroaches are omnivorous scavengers. They are attracted particularly to meats, starches, sugars, and fatty foods. Where a shortage of foodstuffs exists, they may eat household items such as soap, glue, and toothpaste. In famine conditions, they turn cannibalistic, chewing at each other’s wings and legs.
The smokybrown cockroach is readily distinguishable from it by its uniformly dark brown–mahogany coloration. Furthermore, unlike the American cockroach, which possess a light-rimmed pattern on its thorax, the smokybrown cockroach’s thorax is dark and shiny.
The smokybrown cockroach is very common in Japan as well as the Southern United States and tropical climates; notably, it can be found in Florida, and other moist Gulf Coastal States. The smokybrown cockroach prefers warmer climates and is not cold-tolerant. It may, however, be able to survive colder climates by going indoors. In addition to this, it fares well in moist conditions and appears to be particularly prevalent in moist concealed areas. It often lives around the perimeter of buildings.
The smokybrown cockroach is a detritivore and can feed off a wide array of organic (including decaying) matter. Like most cockroaches, it is a scavenger. It tends to lose more moisture than its relatives and requires water every 2–3 day
Like the German cockroach, it is about 1.6 cm (0.63 in) long, is tan to brown in color, and has wings. However, its wings are longer than the German cockroach, and there is a difference between a groove in the abdomen between the two species.
Asian cockroach is found in tropical and subtropical climates, and was first identified in the United States in 1986 in Lakeland Florida. It has since expanded throughout much of Florida and is spreading into other southern states. This species tends to prefer the outdoors.
This omnivorous species feeds, under certain conditions, on the eggs of lepidopteran pests of annual crops.
