Grynocharis quadrilineata? - Grynocharis quadrilineata

Meredith, Belknap County, New Hampshire, USA
January 1, 2004
Size: 9.5 mm

Family is alternatively Trogositidae or Lophocateridae, depending on taxonomic revisionist. Found in freshly felled dead tree at what had been at least 8 ft. above ground level -- possibly over twice that height. This individual is preparing to fly inside my light arena, which is also the aim of the two clerids (Zenodosus sanguineus)in view.

Mite?

Any idea on who the hitchhiker is?

Small clerid beetle

Zenodosus sanguineus, a clerid with bright red elytra. You can see another below the main subject. I have a shot of another hanging onto a lampyrid's elytra *during* flight, although not so adeptly as a mite might. Yet another shot is of one taking off from the pronotum of an Eyed Click Beetle, Al*aus oc*ulatus. Maybe I'm post 'em sometime.

Possible, but ...

Compare to this or

- I don't see a scutellum (maybe just not obvious to me) and the elytral carina 'appear' to merge apically - hard to tell. Looks like the right family though.

Thank you Phillip.

I've added a shot showing the scutellum and another showing the posterior, in case those will help you ID this beetle. Since I reference two families, Trogositidae and Lophocateridae, in which did you agree it appears to fit? Or do you mean it looks like the genus is right?
