I have a Bird's nest (European Robin) in my garage that I need to remove. Chicks were successfully raised this summer, and the nest is still in use.

What I am thinking is that it could be interesting to dismantle the nest and look for dipterans. So what would be best time to do it?

I will not interfere when/if there are eggs or chicks, on the other hand I am hesitant to let them keep the nest one more season. I have to leave my garage door open for this.

Also, what diptera families could I find? And are the chances good enough to find ANYTHING that is is worth tha hassle?

Any opinion on the matter would be much appreciated.

Diptera families - Milichiidae, Carnidae (I never saw this family), Scenopinidae, Hippoboscidae... at least these are those I know at the moment.

You could try just placing the nest in an emergence trap and seeing what comes out. A similar thing (but on a larger scale) is outlined here - http://sites.goog...ant-s-nest

Also Neottiophilinae, Piophilidae, Chloropidae which I found in summer and maybe many more. Look also for beetles, Oribatid mites, bird mites, fleas... Keep the nest humid if you want to rear animals!

Hi cyprinoid,

birds' nests are a very interesting resource not only for flies. From own experience and as already mentioned humidity plays a key role: for instance nests from birdhouses are usually to dry for rearing anything, which may also true for your nest in the garage.
A valuable reference for what might occurring you will find in the papers by Hicks. Full references and some other insights regarding bird's nest can be taken from here.

so long,

Thanks all.

Does anyone have plans for a diy emergance trap, or a link where I can buy one?
