Darkling beetle - Arthromacra aenea

Darkling beetle - Arthromacra aenea
Chantilly, Fairfax County, Virginia, USA
June 1, 2009
Size: ~ 1 cm
My best guess is Arthromacra.

Arthromacra aenea --det. W. Steiner
his comment: "look[s] like A. aenea to me...the most common and widespread sp. but variable. The other spp. are more restricted to S. Appalachians and more bright metallic green."

Moved from Arthromacra.

yup; not sure which one, though
all 3 spp. possible in VA and I'm clueless about the differential Dx

Thanks, v!
