A black fly (sometimes called a buffalo gnat, turkey gnat, or white socks) is any member of the family Simuliidae of the Culicomorpha infraorder. They are related to the Ceratopogonidae, Chironomidae, and Thaumaleidae. Over 1,800 species of black flies are known (of which 11 are extinct). Most species belong to the immense genus Simulium. Most black flies gain nourishment by feeding on the blood of mammals, including humans.

Guess what? They are out in swarms! Wednesday May 1st, 2013 eating dinner outside for the first time, there were a few but not really biting. Out in the back yard however… they had friends. Notreally quite yet biting… maybe a few bites, mostly just flying around in your ears, eyes and nose.

Time to find the long sleeves, long pants and bug hat again. Even the front yard was swarming with them.

Updated: 2013 May 09 – 8 days later they are still around and as plentiful and hungry as ever.
It is not possible to work outside unprotected … one must have a head net and long pants and sleeves.
