On the way to and from the Dipterists Summer Field Meeting in Aviemore, Alan, Roger and myself did not have particularly good weather through Scotland's Southern Uplands, so we spent some time attacking thistles to record Cheilosia albipila and C. grossa larvae.

I took the opportunity to take some photos of the process and also kept some specimens of larvae to photograph in detail. I have put together a note on the techniques of finding and identifying these larvae.

Download it here (PDF file, 1.1Mb).

We would encourage other recorders to check thistle patches for larvae. This is much easier way to find these two very early species which are often overlooked.

Thanks for that Stuart - very much appreciated and very informative.

I don't suppose you have tried to rear these through to adults have you ? If so, any tips ?

Cheers

I have never had any success in rearing things! They always go mouldy and die.

There has been quite a bit of discussion of rearing on the Dipterists Forum site - so you could try asking there.

Graham Rotheray at the National Museum of Scotland is the real expert.

This is excellent. I must remember to take my gardening gloves out with me and have a go at this. Very Happy

Just to add my thanks for this great piece of work, Stuart. Will have a go on bad summer days (no shortage of those!).
Regards,
John

Hi Folks

Looking for larvae can be a painful business - I've finally extracted the last thron from two weeks ago!

Stout gloves are a must. Do take a careful look at single stems as you may get C. albipila - alternatively you will get frosted orange and the moth scheme would doubtless benefit!

Regards

Roger
