Sawfly? - Sphacophilus cellularis - male

Sawfly? - Sphacophilus cellularis - Male
Hampshire County, Massachusetts, USA
July 15, 2005
Size: ~7 mm
There were quite a few of these (all with the "double antennea") on a Morning Glory at a friend's house. The antennae seem pretty distinctive. I think it is a sawfly, but that's as far as I've got...

Moved
Moved from Argid Sawflies.

Sphacophilus cellularis (Say)
Male. Females have much more orange (and simple antennae). Larvae feed on morning glory.

Yes!
You got a male argid sawfly! Males of many species have the last antennal segment forked. The host plant should take you to genus easily enough, if not to a species.
