Recording Cheilosia larvae from thistles

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.

Re: Recording Cheilosia larvae from thistles

This is a very interesting and useful article, but the big question I have is - does this kill the thistles or can they always re-grow from such destruction? I would like to preserve the marsh thistles on a site, though I'm not concerned about the spear thistles.
Also, are any other species of thistles used, e.g. woolly thistle?

Re: Recording Cheilosia larvae from thistles

Cheilosia fraterna is relatively common local to me, so in identifying Cheilosia larvae in local marsh thistles I would be happier if I knew what Cheilosia fraterna grubs looked like. The only photos of Cheilosia larvae I can find are those of grossa and albipila. Anybody have any photos of Cheilosia fraterna larvae or other Cheilosia larvae found in thistles?
