The Australian Cockroach is similar in appearance to the American
cockroach, reddish-brown in color, and winged. However, the Australian
cockroach is slightly smaller than the American, growing to be approximately 1
1/4"-1 3/8". The Australian Cockroach also has a yellow margin on the
thorax, and yellow streaks at its sides at the base of the wings.

Controlling Cockroaches
When RoboRoach appeared as a Kickstarter project in June, the project to control a living cockroach’s movements using a smartphone, generated buzz and was successfully funded. Now the project is poised for a large-scale launch in November, but some dissidents have raised ethics concerns about the way it frames animal experimentation.

Madagascar hissing cockroach
The Madagascar hissing cockroach is a large, wingless cockroach from Madagascar, an island off the coast of Africa. Little is known about its ecology, but this insect probably lives on the forest floor in rotten logs and feeds on fallen fruit. The Madagascar hissing cockroach is a fascinating insect because of its unusual ability to produce sound. However, its unusual appearance and elaborate behavior also contribute to its appeal.

American Cockroach
Adult American cockroaches have wings and will occasionally fly. However, they are awkward fliers and prefer to run when disturbed. Male and female American cockroaches are about the same size and look very similar. Both have a pair of cerci, finger-like appendages, at the tips of their abdomens. The cerci are used to detect air movement in the cockroach’s surroundings. Male cockroaches have an additional set of appendages called styli on their abdomens. The styli are located between the cerci but are smaller and more delicate. The presence of styli is the easiest way to distinguish male from female cockroaches. Immature American cockroaches resemble adults, except they are smaller and wingless. The American cockroach egg capsules are mahogany brown and about 1/3 inch long. The egg capsules resemble small ridged purses and are often stuck to the outside of boxes, or along baseboards in locations where the cockroaches are infesting.
