Leaf Beetle? - Scirtes tibialis

Leaf Beetle? - Scirtes tibialis
Bolton, Worcester County, Massachusetts, USA
June 18, 2005
Size: 3.5mm
Looks like a hind leg is sticking out, and might be a type of flea beetle.

It does look like the picture in Marshall's book (1), and he says there are only 2 northeatern species of Scirtes.

Scirtes sp.
This is a "marsh-loving" beetle, family Scirtidae. Judging from the fact that the hind femora appears to be swollen and enlarged (like a flea-beetle), I would say this is a species of Scirtes. There are only a few species in the genus that occur on the East Coast, but apparently they are wide spread, making it difficult to guess a species name for this. There is another scirtid genus with enlarged hind femora, Ora, but its three species are only known from the extreme SE US to Texas.


If it is Scirtes....
then it would probably be Scirtes tibialis, which has all black elytra.
