We run into clegs in Glen Affric area on Sunday... I didn't know blueberry picking requires so much arm movement
They were "ordinary" clegs though, the size of housefly. You wouldn't want to be bitten by one of these (spotted on the car park for Grey Corries):
Meet the band-eyed brown horsefly. Until last week I didn't even know such species existed.
Disgusting! About 4cm long and very noisy...
Luckily they were only interested in nearby herd of cows and used our car as a resting place. We made sure none of them travelled home with us!
I'm afraid no amount of deet, smidge or other repellent would deter them. I felt very sorry for the poor cows...
