Phthiraptera Parasitic Lice, Biting Lice, Sucking Lice.

Biting lice: broad head, short antennae, reduce eye, two small claws.

Lice are seen in every county around the world. Use humans as host. Cannot survive long without their host. Lay about 4 eggs a day, 88 in a lifetime. Cause problems in schools or anywhere where people come in contact with one another.

Start as nits or eggs laid by an adult female. They then grow up to be a nymph eight or nine days later. Nymph will grow into an adult nine to twelve days later. An adult is about the size of a sesame seed and live about thirty days on their host.

Biting lice evolved first on birds but less than 135 million years ago they moved on to other mammals. Some broke skin to suck their host blood creating sucking lice.
