The antennae are long and hair-like and may be longer than the body. They have chewing mouthparts. |

Comments: Cockroaches are found under debris, stones, logs, in cracks and crevices. They are associated with humans and exist under artificial conditions wherever they go. They can be serious pests in houses where they contaminate food and can have an unpleasant odour. Certain species have been widely distributed by human commerce and tropical species are sometimes brought in on shipments of bananas or other tropical fruits. | |||
