The Campodorus females are still lurking, laying eggs when they get a chance, although I haven't seen any of the Mesochorus females for about a week, now. This shot shows full-size larvae with a Campodorus female in the centre of the leaf:
Notice a family resemblance? This is another sawfly larva that I find from time to time on either Bramble or Raspberry. No id, yet.
Wonderful shots, particularly that first one. Do they overwinter as larvae or pupae - and on the branches or the ground?
ReplyDeleteHow many broods do they have - this must be at least the second isn't it?
They overwinter in ground litter, some as pupae, others as pre-pupae.
ReplyDeleteThis is the sole generation at this location, but in other locations I get 2 gens. I think it's because this place is cut to the ground every couple of years and it takes a while for the branches to get tall enough.
I think this sawfly might be Arge gracilicornis,I have found it on Bramble.

Yes, John, I'm sure it is: I posted an update last year on http://donegal-wildlife.blogspot.com/2010/10/update.html.
ReplyDeleteThat's one of the problems with blogs: as time passes you learn more and older posts get out of date.
Btw, it's excellent to hear from someone else who is interested in Sawflies, etc. I thought I was ploughing a lonely furrow.
