Adult Head Louse

A magnified picture of an adult head louse. In reality, mature head lice are about the size of a sesame seed.

This is probably a female head louse, since it is a little 'fatter' than a male. It can be seen with a strand of hair for size comparison.

Note the characteristic six legs of this crawling insect. If you magnified this louse even further, you might be able see the small claws on the end of their legs that lice use to grasp hair.
