Found on a roadside verge through chalk downland at Bisons Hill Bedfordshire.
No interactions present.
Many thanks Sue, I think your ID looks spot on!! I'd never heard of these.
A quick bit of research shows that there are up to 13 species of British "Pill Beetles" Byrrhidae and Limnichidae and I found a key on Mark Teflers website (http://markgtelfer.co.uk/beetles/byrrhidae-pill-beetles/)which shows some of the key ID features. Most of these can be ruled out on features shown, but my 2 pics don't cover some of the key points such as tibia shape, so I will upload a few more that hopefully will help others confirm your ID.
Many thanks for your help, it is greatly appreciated!
Kind regards, Martin
