Rare cranefly closely associated with Grass of Parnassus.
how does one identify Limoniids? Last year I did hear that a new book was being worked on. I've got some to sort through in the hope of Gnophomyia viridipennis, which likes Poplar, you may not be surprised to hear..

....with great difficulty! I just plough through the rather arcane keys available on DF. The more you use them for common species, the easier it gets. I'm not sure the book is anywhere close from what someone said over the summer. Maybe delayed by the unnecessary desire to have English names for every species?
I would find Gnophomyia in the key and work it backwards, if you think you have the species.
Off to look for a Poplar...

It's possible you missed this posting - I used the keys you indicated plus found some useful stuff about the genus online:
Do you come across many Craneflies with mites?
Thanks, Jeremy. I had missed this, yes. A very nice cranefly and useful references.
I often see the odd red mite on craneflies, but not similar to those on your Gnophomyia. Wetland sites locally are alive with red mites in late summer and seem to be on almost every fly, some days, from the tiniest Dolichopodids upwards. They come off specimens readily once out of the freezer (but take far longer to die, in my experience, than the fly they are on).
