Is this long black insect with semi-long antennae and a large segmented abdomen caught in the kitchen a larva or an imago? And what is it? This is in Northrhine Westfalia in Germany/Europe: we have those large longish and comparatively flat bugs (taking my hand below the plastic as reference, it should be about 4cm or 1 5/8in in length) or larvae in our kitchen occasionally. For a larva, it seems to be lacking any soft parts. It can raise its behind "threateningly" in the style of a scorpion but I doubt it's anything but mimicry. Its large head reminds me of ant soldiers, though it is obviously out of scale. I think it's mostly in the evening or night that we find one (and it's often because a cat stares at it in an obvious manner) and while it's usually the kitchen, that may just be because we are most frequently there. ![large larva/imago caught in kitchen](

That is an adult rove beetle (Coleptera, Staphilinidae). < Rove beetles have very short elytra (forewings), so they don't look like other beetles. This one looks a lot like _Ocypus olens_ , which is common in Europe <
