Definately a midge. Possibly Culicoides midge - like the ones around here.
"In Scotland 37 different species of Culicoides midges have been recorded. Culicoides impunctatus, which is responsible for up to 90% of the bites on humans, occurs throughout the country, although it is most abundant in the west and the north, where the boggy and acidic ground provides an optimal environment for breeding."
Got about 20 bad bites on my legs from them last week cutting the grass.
