This is the Bloody-nosed beetle, Timarcha tenebricosa, and chalky grassland is classically their habitat and anywhere else that their adult and larval foodplant Gallium spp. is found. They are members of the beetle family Chrysomelidae and like all others in the group have adapted pad-like feet loaded with hundreds of special adhesion hairs that enable them to climb on shiny surfaces of leaves (and even polished glass). They are a classic summer beetle observed on sunny days (long may they stay with us - the sun that is, and the beetles of course). They always remind me of clockwork beetles as they slowly march along on their padded feet.
