Hi all, I'm currently processing water tray samples collected in oilseed rape in Wessex, UK, June-July 2013. I'm hoping to get all fly larvae at least down to Family but I have several that I haven't been able to get a reliable identification for. The photos I have aren't great but I'm hoping that someone may have at least a rough idea what family they might belong to. The first has cropped up in several samples, they are approx 2-3mm long. The have simple mouthparts, the posterior spiracles protrude on stalks and the segments have a wavy/ridged pattern. I thought they might be Agromyzids since the front spiracles seem to be adjacent but they are a lot darker than other examples I have seen and none seem to have this wavy pattern. Sorry I can't be more specific than that! More to follow.... Edited by Rouncie on 25-06-2014 14:06 |

This second one is a similar size (2-3mm), again found in a few different samples now. The posterior spiracles are contained inside the last segment so I thought maybe Sarcophagidae? |

I also found a few of these, but I'm not sure if they are fly larvae or not!

the first 2 I don't know, the third and last is a Lonchopteridae larva

The second one might be Sarcophagidae - females carry "ready-to-lay" first instar larvae, and often give birth in water traps - it's worth checking to make sure there were female Sarcophaga in the same trap, and maybe even dissecting some to get some reference material
