Cockroaches

American cockroach, 4 cm (1.6 in) long Cockroaches are extremely adaptable insects. They have broad, flattened bodies with relatively small heads and long antennae. The spines on their legs help them move through soft or lumpy terrain. They can live almost anywhere and many will eat any kind of food they can find. Some are tree-dwellers and have wings, while other, wingless kinds burrow into the ground or hide in small spaces, coming out to feed. Some kinds are found in houses, where they eat our food and spread germs and diseases. A few species are capable of going without food for a month.
