Order Blattodea



The cockroaches are fairly large, oval, flattened insects with long antennae. Legs are long and slender and adapted for running. They have chewing mouthparts. Wings can be well developed, short or lacking. If winged, forewings are leathery while the hindwings are membranous. Metamorphosis is gradual, the life stages being the egg, nymph, and adult. Many live outdoors, but some species have adapted to live indoors and are considered to be serious household pests.
