Is it a Black beetle nymph? Or a female? Or some other beetle?
No interactions present.
BugLife are asking for all oil beetle records to be submitted.
take a look at the website they have a nice Identification leaflet to help Id different oil beetles.
Looks like Meloe proscarabaeus, based on locality, puncturation (heavily so) and overall shape of pronotum.
