large blue/green caterpillar
Description:

A very large blue caterpllar, which seems to remind everyone of "Alice in Wonderland", can't think why! It was about the size and thickness of my little finger and I have no dea what it will turn into. Any ideas? Would it be something quite large?

if it is as large as a little

if it is as large as a little finger, I suggest it may be a hawk-moth.

unknown caterpillar

Thanks for your comment. If you hover over the image you will see I have titled it blue/green caterpillar. Everyones colour perception is slightly different. Some people may find this is not an easy colour to identify accurately.

Still lots to learn!

pontania proxima

Hi Torchy, Pontania proxima larvae live inside a gall and are much smaller, so likely not this.

Interesting David, many

Interesting David, many thanks for the info. Could it be a Hawthorn Sawfly larva then? My Kingfisher field guide says it has a pale green larva with a brown head but doesn't mention what size. Unable to find my book of British insects at the moment and my Collins guide to British Wildlife doesn't mention it at all.
It is on a mature river/field boundary site.

Still lots to learn!

Hawthorn sawfly - Trichiosoma tibialis

Possibly, but see note about possible cryptic species: http://www.wsbrc.org.uk/images/2011/4/ReportOfWiltshi.pdf

I.e. there may be two very similar species, one on Crataegus and one on Salix.
