Thanks for the very useful replies.

For the caterpillar, I think I'd discounted Hepliaidae on the basis that it was under bark rather than on roots etc: but certainly looks a good fit. I've seen something similar under bark of dead elm.

The beetle was very small: reason picture was blurred is this is 4x digital zoom, running around on my hand and it was under a dark yew! Definitely at edge of capability of the camera (& the photographer). Unfortunately I did not have my hand lens with me so photos were the only means of gathering info.

I've had another look to try and estimate size and it appears to be no more than 2 mm, and probably closer to 1.75 mm than 2 mm. So perhaps more likely to be vittula. Location was near edge of woodland with open fields and the wide verge of the A4 both close at hand.

Either way, next time I see anything like it I'll know where to start!

Cheers,
