Head louse spiracle. Coloured scanning electron micrograph (SEM) of a spiracle (centre) on the thorax of a head louse (Pediculus humanus capitis). Spiracles are openings through which the insect breathes. The head louse is parasitic insect which inhabits the hair of the head,gluing its eggs (called nits) to the shafts of individual hairs. It lives on blood,which it sucks from the scalp. The wounds left by the lice cause intense itching,which can lead to dermatitis and infection. The lice can spread from head to head by close contact. Lice and nits can be killed with medicated shampoos. Some treatments are designed to block the spiracles and suffocate the insects | |
