A subgroup of the gnat family. Only the females bite.
Where?:Throughout the UK but notoriously in Scotland. Worst on damp and cloudy days.
Bites: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.
Protection: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.
Danger rating:1/10
