See this bug in the Encyclopedia

Natural Habitat

Lives on human scalp hair, especially near the nape and behind the ears; it does not normally survive long away from a host.

Diet & Feeding

Feeds by piercing the scalp and consuming small amounts of human blood several times daily.

Behavior Patterns

Wingless, crawling insects that cannot jump or fly; females glue eggs to hair shafts, and the life cycle from egg to adult takes about 3–4 weeks.

Risks & Benefits

Causes intense itching, irritation, and scratching-related sores but is not known to transmit significant disease in most settings. Control involves treating the scalp and removing nits with a fine comb; confirmatory identification is recommended because the image is indistinct.
