Conk beetles - Eleates depressus

Conk beetles - Eleates depressus
Jefferson Notch area, Coos County, New Hampshire, USA
May 12, 2007
Size: 5.5 - 6.0 mm
I found these two nestled between the bark and the bottom lip of a fresh, moist conk that was growing on a tall conifer stump remaining from a wind-and/or-snow-snapped tree. Certainly they are in superfamily Tenebrionoidea. My guess is they are a male/female pair.

So this is definitely a Tenebrionidae in the subfamily Bolitophagini. I think that the lack of tubercles on the elytra (compare with Bolitophagus) makes this Eleates. I think that Eleates depressus is the only species to occur up there. Neat find! You wouldn't happen to still have the fungus in which you found these would you? If so, would you be able to post photos of it, or post the name of the fungus? Any larvae of these guys?

Fungus: Fomitopsis pinicola?
I'm pretty sure this is the fungus species on which I found these two:

Thanks, I asked because this is one of the species I wanted to get while going to school in the North. I've been told that MD was as far south as it gets. The larvae of this genus is yet to be described but I know some people (including myself) who would be interested in them. The locality data of the specimens here at Cornell are too general so its great to have the name of a specific site where this beetle occurs.

Yes, I have a Fomitopsis pinicola
and both beetles are now at home. We're hoping for babies :-)

Great! hope it works!

I did collect some conks
on May 5th when I was in the same location. I'll look through them to see if I have one these beetles might like. Maybe they will lay eggs and we can get some larvae to describe.

No fungus, no photos :-(
I would have kept the fungus but was already packing a heavy load six miles uphill. The outer band (about 1/2 radius?) was red and the inner circle was grungy gray-brown. No evidence they'd begun chewing yet, let alone laid eggs.

Thanks so much for figuring out the ID :-) I found an image at the University of Wisconsin site

Moved from Beetles.
