Phthiraptera
Phthiraptera is an order of parasitic insects commonly known as lice. These wingless insects are small in size and feed on the blood of their hosts. Lice can be found on birds and mammals, including humans, and are known to cause irritation and discomfort. They have specialized claws adapted for clinging to hair or feathers, making them difficult to remove. Lice infestations, known as pediculosis, are a common problem worldwide and can be transmitted through close contact or shared items.
