Processing Pan Trap samples

Hi all

I have a project this year, part of which is using water (pan) traps for sampling Diptera. I am intending to place specimens in 70% IMS for subsequent identification to at least family level.

I was wondering if anyone with experience of this could suggest the best means of processing the specimens at the microscope, in terms of whether it is best to keep specimens wet or best ways of drying out to help with identification.

Many thanks

Re: Processing Pan Trap samples

I just pick flies out of the IMS and put them onto paper towels, then gently dab them and move them around on the towel. Then leave them to dry for a while, following which they are easy enough to pin. To save time I don't pin most of them, but try to ID them unpinned.
