Thread subject: Diptera.info :: poss Tachinid Electophasia crassipennis

Hi there
I saw this one fly feeding on umbellifers by the roadside at Royal Common, near Elstead ,Surrey. The area is mature deciduous woodland with plenty of open fresh water.
It may be the tachinid Electophasia crassipennis. Would welcome other opinions.

EDIT Paul Beuk: I happened to have a copy of the picture and cropped it. Moreover, I removed the spaces and the commas from the name and now it should be okay. ;)

This fly was seen on 7th July and was approx 8mm in size.

Hi Stuart - try removing any spaces in the file name and keep it under 200KB :) I'm very excited to see the photo - I have been watching-out for any Ectophasia for a number of years! :D

Thanks for that Paul ... sadly it's just a female Phasia hemiptera :( (Ectophasia spp. don't have a petiole)

Petiole is missing in the glossary. What is it?

Posted by ChrisR on 10-07-2007 11:10

In this case I mean the petiole in vein-m ... it's the "stalk" created when vein-m (median vein) meets r4+5 before the wing edge :) In most tachinids vein-m never joins r4+5 or it meets excactly at the wing edge.

Try: petiole header=[petiole] body=[Literally: stalk. Can be used to indicate the common stem of two veins (basal part before fork) or the vein that is formed when two veins running towards the wing margin merge, for example R[sub]4+5[/sub] and M[sub]1+2[/sub] in some families of the Calyptrata.<br /><img src='infusions//terms/images/no_image.gif' style='vertical-align:middle;' />] delay=[0] fade=[on]

(quick and dirty).
