A Blog for moth recorders in Bucks, Berks and Oxon
Hi Dave, I think larva is a Vapourer.
Actually, Nigel, I'm not so sure that is a Vapourer caterpillar. I'd prefer to see a better picture!
Just possibly a Yellow-tail Moth caterpillar?Andy.
I'm thinking it's a Dark Dagger larva, Dave.
That's my thought too but it needs a better image to be sure!
I'm posting all 4 pics I have, so hopefully one of them will be enough!
Thanks for adding the extra pictures, Dave, but it hasn't really helped much! The images are rather dark but even some tweaking in Photoshop doesn't help very much. I presume that this is not a final instar larva (caterpillars can change in appearance quite a lot from one instar to the next, so knowing the size might have helped a little bit). My best guess is still Dark Dagger but it doesn't look quite right to me so don't take that as a firm ID.The fly mine on birch looks dipterous so could well be Agromyza alnibetulae. I take it that you will already have checked here: http://www.leafmines.co.uk/html/Plants/betula.htm . This web-site (and the Dutch equivalent at http://www.bladmineerders.nl/) is well worth looking at before asking questions about leaf-mines, especially as "high season" for them is only a month or so away now!
Looks like one of the footman to me. First thought was Red-necked for which the markings fit but the colour is different - might be the yellow form. Keep it and rear it. I found a RNF larvae in my trap last year and reared it through very easily. BW, Marc
Marc, I don't have the caterpillar I'm afraid. I have had RNF caterpillars on the burial park trap before, although it didn't look the same as those. Dave, it's always very dark in those woods and I was in a hurry to get to an appointment! I do look at the leafmines and flymines websites, but so many of these things look the same to me! There are a few I can do OK now, especially after going out with Mr King around the COAM site. I think I'd do well to attend Mr Fletcher's Leaf Mines day in the BIG calendar...
I'm pretty certain this is the larva of the Orange Footman.
Thanx Dave, that does look like a good bet, and the species is certainly present in the park!
