I have no idea what this is! Been through a couple of insect guides but I'm not very good at IDing insects so I may have missed something.

I have no idea either!

Oil Beetle larvae

The larvae of Meloidae or Oil-beetles are brood parasites of solitary bees, so you don't see them above ground except in the first instar tringulum stage

Indeed - Meloidae was a bit of a guess and the other i.d. did jog my (at the time) failed memory!

Matt, I agree that it's a bloody-nosed beetle, but do you know if the larva of the Lesser Bloody-nosed Beetle (Timarcha goettingensis) is similar? I don't know!

I think the location makes Timarcha tenebricosa more likely.

I think the larvae of

I think the larvae of Timarcha goettingensis are very similar and probably occur in similar habitats. This is certainly much greener than T. tenebricosa larvae I've seen before, although I doubt colour is a defining character.

Timarcha larvae

I've had a bit of a trawl on the web and found various images of green Timarcha larvae, including a couple of non-British ones. I can't find anything about how to tell them apart (the colours do seem to vary in intensity), so maybe a revised id to 'Timarcha' would be appropriate unless anyone else knows how to separate them?

Cox (2007) gives a reference

Cox (2007) gives a reference for seperating these larvae, but it is in a rather obscure academic text (Novel aspects of the biology of Chrysomlidae (1994), Jolivet, Cox and Petitpierre eds.). I don't have this one on my bookshelf and I reckon you probably can't tell them apart from a photo anyway!

Jolivet et al

Not surprised it's isn't on the shelf as it's over £300... one for an inter-library loan.

I also pretty certain that they can't be separated by photo.

Been trying to identify the same bug

Saw the same bug on the coast path in Pembrokeshire this weekend, much greener than all the pix I've found of the Bloody-nosed Beetle larva.
