Coloured scanning electron micrograph (SEM) of Chicken body louse, adult and juvenile (Menacanthus stramineus). The chicken body louse is wingless and flattened. They have two sharp claws that they use to scratch the surface of the chicken for food. They occur wherever poultry hosts can be found. This chewing louse feeds on skin fragments, feathers and debris and causes the host's skin to be irritated, red, and scabby. As a result, infested birds lose weight and layers decrease egg production. Extremely heavy infestations can kill poultry. Magnification: x8 when shortest axis printed at 25 millimetres.
