It’s Latin name means something like blood-drinker of the rain, but these flies are also quite happy to drink your blood in the sun!
Seeing so much of nature is one of the benefits of working (or just being) out of doors. But it also makes you prey to some of the nastier biters, stingers and blood suckers.
The cleg is a type of horsefly and it can bite right through thin clothing. If you’re working or walking where there are livestock and long grass, there’s a good chance there will also be clegs. Although they seem dozy and slow, they are incredibly able to stick with you no matter how fast you move. I’ve found that coconut oil is the best thing to put them off, but it’s not foolproof.
It’s the female that does the biting: she needs blood in order to make her eggs. In her favour, she does have prettily patterned wings:)
