Louse

Typically found on the bodies of warm-blooded hosts, such as humans, pets, or livestock, often clinging to hair or feathers.

Obligate parasites that feed on the blood or skin debris of their host animals.

They are wingless and move by crawling or clinging with specialized claws. They undergo incomplete metamorphosis (egg, nymph, adult) entirely on the host.

Risks include irritation, itching, and potential transmission of diseases like typhus in some species. They have no significant benefits and are generally considered pests.
