Athous haemorrhoidalis - Click Beetle ID? (Cambs. UK) (1 Viewer)

Hi All

I found this small (perhaps 15mm long), stationery beetle on a damp woodland glade, in Cambridgeshire.
Conspicuous hairs on the elytra, head dark, near black.
Habitat and geography match sources but I am unsure if there are others that are similar.

Yours, Gareth

Possibly but several closely similar species that need to be excluded.
I have looked a Mike's Insect Keys. The pictures in the keys help - A. haemorrhoidalis is good match for my pictures, along with A. subfuscus, A.bicolor and A. vittatus.
I can key out A. vittatus and A. subfuscus, as the first segment of the antenae is black not reddish. The latter is also pretty rare in the UK.
I can key out A. bicolor, as the elytra is not brownish-yellow. It is also seen from June onwards.
So that pretty much leaves us back at the beginning A. haemorrhoidalis.
Thanks for the lesson Ficedula ;)
