and here is a lateral view from a different fly which I think may be the same species - this one from today.

The combination of : Frontal vitta black+ 2 strong rows of acrostichals+arista not haired+ thorax strong striped 2+2 katepisternals + calypters same lenght (lower one bit longer) ..............make me say, Lasiomma sp. (On the first photo, eyes seems to be hairy, but to unsertain to say, it is...) But you know it already by now......it is a female, so notting is for sure  Joke van Erkelens Edited by javanerkelens on 19-12-2009 18:28 |

Thanks again Joke  Diptera have been a great lesson for me in living with uncertainty! I hadn't noticed the hairs on the eye; I think there may be something there, but very short and sparse. I'll look through my pics of similar flies at higher resolution. |

I didn't think the Anthomyiidologists' Union Rules allowed females to be pursued beyond genus level  None of my pictures seem to show any hairs on the arista - but it's hard to prove a negative! Here's another one from November:

Many females of Anthomyiidae are very simular to each other ! To be surtain you have to collect male and female together. For most female Anthomyiidae a genus level is very nice! In this case....very short haired (L.anthomyinum) means ....the longest hairs have the thickness of the base of the arista And.....can we be sure it is almost bare or very short haired....I can't tell L.anthomyinum / strigilatum is very nice for a female Anthomyiidae Next time.....just a male Joke |

Thank you Joke, you can have December 25th free But now that I know that you can get so far with female Anthomyiidae, it seems unsporting to give you a mere male Merry Christmas! Stephen. |
