Grape Flea Beetle - Altica chalybea? - Altica

Grape Flea Beetle - Altica chalybea? - Altica
Tallahassee, Florida, USA
February 25, 2013
Size: about 4mm
This very small beetle surprised me by suddenly springing into flight. It's thick hindleg femora are visible in this image. The beetle is clinging to a coffee stirrer. I'm pretty sure it's Altica chalybea.

as Mike Thomas has just pointed out [pers.comm.],
"Balsbaugh and Hayes(1) characterized three Alabama spp. of Altica as having the pre-basal furrow 'obsolete' or 'obsolescent.'"

for what it's worth, this bug keys out (try the key) to A. foliaceae, which is common & widespread species but not listed in(2) for Fla.!; in any case, A. chalybea can be ruled out.

Moved from Flea Beetles.

pretty sure this is not chalybea, and maybe not even Altica
