- Colour: Black to reddish-brown

- Description: All cockroaches have a pair of long antennae and six long, spiny legs. The body is flattened back to front and oval-shaped. Most cockroaches in Canada have wings, but cannot fly long distances.
Cockroaches are nocturnal and spend their days sleeping in narrow cracks and crevices. This behavior is motivated by the fact that the critters are what scientists call thigmotropic. This means they like their bodies to be in solid contact with firm surfaces. This drives them to squeeze into tiny places. The smallish German cockroach can fit into a crack the size of dime, while its bigger American cousin can jam itself into a space no thicker than a quarter.
Cockroaches are generally omnivorous; the American cockroach (Periplaneta americana), for example, feeds on a great variety of foodstuffs including bread, fruit, leather, starch in book bindings, paper, glue, skin flakes, hair, dead insects and soiled clothing.
COCKROACH LIFE CYCLE
All cockroaches develop by completing a life cycle consisting of three distinct stages: egg, nymph, and adult. The cockroach life cycle starts with the production of eggs. Adult females produce between 10 and 40 eggs at a time, which they carry in specialized cases called ootheca.
