Nalassus laevioctostriatus (Goeze, 1777) (Coleoptera, Tenebrionidae)

There were two of these saproxylic beetles in my B4B.
I was very pleased to find them there; indeed I've seen them when I'm out monitoring for stag beetles,
towards the end of May, at dusk climbing up a hornbeam (Carpinus betulus) tree in the neighbourhood.
Their larvae feed on decaying wood and the adults on algae, possibly lichens as well.

I'm very grateful to Don Stenhouse, Max Barclay, and Keith Alexander for their help with this species;
it they can be easily confused with Harpalus sp., which is a ground beetle. Click here for closer view.
