A subgroup of the gnat family. Only the females bite.

Throughout the UK but notoriously in Scotland. Worst on damp and cloudy days.

Usually bite at dusk and dawn, piercing the skin and pumping saliva into the wound to prevent clotting. This induces a minor allergic response, causing itching and swelling.

Insect repellents containing DEET (Diethyl Toluamide) are effective.

Because midges send out pheromones to alert others to a feeding site, you are likely to suffer multiple bites. Don't carry diseases fatal to mankind.
