I think that the tessellations on the abdomen identify this to family (Sarcophagidae?), but can anyone help me to pin it down further? And if you can, what are the give-away points to look out for?

The curly golden hairs give Pollenia away but often the hairs get rubbed off and only survive around the sides

By the way, Chris, I have to say I'm struggling at the moment with the terminology when using keys - are there illustrations available which will point out most of the salient points of the diptera anatomy which are referred to in keys?

Well, there are nice figures in the Central European tachinid key (and most keys should explain their terms at the start), but some terminology differs between keys and depends on which names the author was most familiar with. Google will help but if you need a hand then just ask. Which words in particular are vexing you?

use this Jez Lee: http://diptera.in...ad_id=8803 -- Thorax lateral view http://diptera.in...ad_id=9242 -- Head frontal view http://diptera.in...ad_id=8790 -- Thoracic Setae http://diptera.in...ad_id=9039 -- Wing venation (but for other family...) |

Wow! Those are a BIG help, Jorge! I wish I could get such beautifully detailed photographs!

all those words are explained in the links above with photos! Also use the glossary that Paul Beuk made. |

I have just worked my way through the keys for Pollenia, and I have keyed it out to Pollenia pediculata. Does anyone know of any reason why it could NOT be this species?

If it has a bundle of very small pale hairs at the junction of the humeral crossvein and subcosta on the underside of the wing, then I see no reason why it shouldn't be. This minute bundle of hairs gives away the species, which is kind of nice since female Pollenia sp. otherwise are notoriously hard to determine. But look carefully - these hairs are easy to miss!

Regards, Hi Walter - I've looked under my microscope, which is only 20x magnification, but I can definitely see (if I look at the right angle) some fine pale hairs on the underside of the node.
