Omoglymmius, wrinkled bark beetle (Rhysodini). California.
Rhysodine beetles make their living feeding on slime molds under the bark of decaying trees . They are instantly recognizable from the grooves on their backs and from their distinctly moniliform (bead-like) antennae. The taxonomic placement of these insects is controversial, but genetic evidence suggests they are a highly specialized lineage of Carabidae, the ground beetles.

I admit to a soft spot for beetles in the family Nitidulidae. Maybe it's the cute clubby antennae. Or maybe it's just the shared fondness for beer. In any case, the sap beetles are charming little insects.
I found this Amphicrossus imbibing fermented tree sap from a wounded tree in downtown…
Cool.
I have these crawling around one of my cupboards and in a dresser drawer.
Any way to rid them? I have no idea how they came to me, since I live on the 10th floor of my building.
