Isn't it a bit early in the year for the Fever Fly, Dilophus febrilis?

I am pretty sure this is Dilophus febrilis - I can see the spines on the front tibia apex, and the area of clear wing towards the tip. It's 16th February, and there seems to be little else that's early this year. Or can it over-winter as an adult?

Possibly but there are always a few individuals that come out early and it is a quite early species. I have had a Sarcophaga buzzing around in my garden recently smile

Hi Nigel,

Had 3 in the last few days; 1 female and 2 males in North Norfolk - swept from grass.

Phaonia tuguriorum visited me yesterday.

Re: Isn't it a bit early in the year for the Fever Fly, Dilophus febrilis?

Yes, I am seeing early stuff too, such as Eristalis tenax ... since the start of the month in fact. But I always associate these with the warmer weather (which I dream of). In fact Steve Falk in his Flickr page on this species refers to the 2 generations, the first peaking in May and early June. So I think this one is a bit ahead of its time, especially since I'm in draughty Cumbria, not the heat island of Reading!
