Lice (Insecta)
Lice are distributed across two orders, the Anoplura (sucking
lice) and the Mallophaga (biting or chewing lice). Table
2–6 outlines the important characteristics of each family.
Although geographic distribution varies according to each
species of louse, in general, lice are distributed worldwide.

Arthropods 27
• Simple metamorphosis with nymphal stages resembling
adults.
• Spend entire life on the host; transmission primarily
by direct contact, but fomites can also play a role.
• Separate sexes with adult females laying small
(0.5–1.0 mm), whitish, oval eggs (nits); attached
firmly to hair or feathers.
