Thank you Sue!!

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 ( 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
