This may well be the same species as I posted yesterday, see http://www.dipter...ost_130861. 'Slightly' better photos this time, certainly more of them. I've tried keying it out using Belshaw; without a satisfactory answer. If the mouth is projecting - hard to say - then I get to Cadurciella; if not projecting, I get to Cyzenis, but that should have at least one proclinate parafrontal - I can't see any. Or perhaps I've gone hopelessly wrong somewhere previously. 21/4/2010; Devon, England Tim tim worfolk attached the following image:  [131.46Kb] Edited by tim worfolk on 21-04-2010 20:17 |

closer, through possibly no sharper, view of head.

Mouth doesn't look projecting to me, though Cadurciella is probably the most borderline species to run through that couplet  Doesn't fit Cadurciella to me though - I have had them a few times on good grassland sites with plenty of Green Hairstreak.  In the absence of a specimen the Cyzenis looks the best bet so far

What is wrong with Cyzenis albicans ? It has this proclinate orbital clearly in last pic, except that it is lateroclinate (accidental) ? Theo |

Thanks to both of you for clearing this up, I obviously need to learn my bristles - or take better photos. Nice fly and a first for me. Thanks Tim |
