Caterpillar ID

[GardenJock]

Hello, first post. I found a caterpillar on my Victoria plum which looks exactly like a twig. I didn't realise we got this type of caterpillar in the UK. Could anyone tell me what kind of caterpillar this is please? I will upload an image once it has been uploaded to the Gallery.

There are a few noctuids with twiggy caterpillars noteably the red underwing. Yours is a brimstone moth feeding on plum.

Lance, thanks very much. I look forward to seeing it develop.
Cheers.
