Britain, Ireland, northern Europe, Russia and northern China, near bogs and marshes

Can it hurt you?
Can bite or sting
Its bite feels like a tiny prick and can leave itchy bumps for a few hours or days. Long sleeves and a head net help a lot.
What does it eat?
Only the females bite and drink blood. They mostly drink from cows, sheep and deer, but they will bite people too.
