Close up shot of a Heather Fly or to use it's posh name Bibio pomonae.
They appear every year usually during August and are found in the Peak District in Derbeyshire in their millions. They are only around for a short time however, and emerge to coincide with the flowering of the heather. The adult flies feed on nectar, and to my knowledge are completely harmless as they do not bite! Certainly I have had them crawl over me in the past, and suffered no ill effects.
The males have bigger eyes than the females and both are very hairy, presumably to keep warm. This Bibio pomonae fly has very distinctive upper red leg sections, as compared to other Bibio flies which are all black. They fly slowly, partly due to the fact that they dangle their back legs during flight.
I know that most people see these interesting flies as bothersome, especially if they fly in your ear, but remember that they are only here for a few short weeks only.
Hope you like the photo, and thanks for all your votes and comments yesterday, it encourages me no end!!
