beetle - Hydrobius melaenus

Came to light at night. Approximately the size of Harmonia axyridis (didn't measure...).

Moved from Enochrus.

My suspicion
would be Hydrobius melaenus if about 8 mm.

 
H. melaenus
It was about 8mm, from what I remember. Is there any other view/closeup that would make this more certain? I'll move the images to a new species page for now.

 
There
is another species it might be, supposedly around but I have never taken it. To be sure you must have a crystal-clear view of the surface of the metafemora in a ventral view. H. melaenus is associated with running water, the other with ponds. Your specimen was taken at light, so nothing would be obvious, except I have taken melaenus a number of times and the other never.

Hydrophilid?
I'm thinking this is a water scavenger beetle, but I'm going mostly by the "Gestalt" method of ID:-) Very nice image, and a real expert will have plenty of clues to work with!

 
Hydrophilid
Thanks Eric -- that looks right.

 
Enochrus sp.
