Long time no post; things have been very quiet but now signs of life are appearing. I was out today and totally unprepared for insect photography when I found this resting on a birch trunk. A close look showed short antenna - like an Empid or Dolichopodid perhaps, definitely not thread-like as in a sawfly. I didn't recognise it and managed to get only one very poor shot before it flew. Unfortunately the light was poor, high ISO and wrong lens and I didn't even manage to get the focus right. Normally I wouldn't dream of posting such a dreadful picture but I am extremely curious to know if anyone can make anything of it. Apart from anything else I'm just surprised to find anything so interesting on the wing in February. 21/2/2010 Devon, England; wet woodland (birch, oak, hazel) by upland stream.

Many thanks for the quick answer. A quick check shows only one Liancalus on the British list - virens. I'm just annoyed I didn't get a better photo. By the way, is it normally about at this time of year? Tim |

Dear Tim, Yes, you are right, this is Liancalus virens. And its presence at this moment is not unusual as it has been reported in about every month of the year, especially in coastal areas. I had been considered extinct in Flanders until some years ago when it was found about 600m from my current home, on the wall of a building near a nature reserve. It is, though, most abundant around springs and waterfalls where it prefers vertical substrates. Cheers, Marc marc.pollet@inbo.be |

Cheers, Marc marc.pollet@inbo.be I thought it was in Denmark that you were found to be extinct Marc  ...only kidding  Regards Roger |
