Chicken Body Louse

The most damaging louse of domestic poultry, feeding on feathers, skin, and blood. Heavy infestations cause feather loss, reduced egg production, and anemia.

💡

Did You Know?

This louse is unusual among bird lice because it actively feeds on blood by gnawing through pin feathers, not just on feather material.

Notch-horned Cleg

A grey horse fly with mottled wings that approaches silently before biting. It is one of the most common biting flies in Europe.

💡

Did You Know?

Unlike most horse flies, the cleg approaches completely silently, landing and biting before being noticed.
