Root-eating Beetle - Monotoma bicolor

Root-eating Beetle - Monotoma bicolor
Groton, Middlesex County, Massachusetts, USA
April 7, 2010
Size: 2mm
I was on my deck and I saw this tiny beetle flying by me, so I grabbed it out of the air.

Moved tentatively; good call, Tom. will show it to Yves

Thanks =v=
I don't know if you've seen this key to Atomaria also by Christopher Majka.

i think i've seen all of his stuff; we're in touch with Kristof
he's kinda... [very kinda] countryman of mine :) the atomariine paper is in the Guide at(1)
(and this M. bicolor was my 2001st guide page -- but i'll have a very hard time matching your track record)

Not bad, 2001guide pages!
That's a good chunk of the 17,500+ species pages in the guide. I may find a lot of bugs, but you're the one who knows what they are.

i think at least half of my pages are not species pages...
...but rather family-group taxa ([sub]tribes thru subfams), that used to be much badmouthed and vilified on the Forum :)
perhaps a hundred of so are 'No Taxon' pages; so the statistics actually needs adjustment -- which is also the case with any statistics: it's what behind it that matters

Monotoma producta
? Please wait for a second; I dont have as much experience with this family.

M. bicolor?
I was looking at this PDF from Christopher Majka. And M. bicolor looks close.
In the description, it says they are in rotting vegetable matter, and my compost pile is 50' from where I snagged this beetle.

Nice PDF!
Yeah, bicolor looks more like it based on those images. Wish there was a key. :-)

Partial key
There is a partial key that covers 12 species found in Canada. Give me a few minutes and I'll dig up where I found it. See the pdf version here. I'll add link to genus page.
