Honeysuckle Sawfly? - Trichiosoma triangulum
Gold Rush Trail, Sanders County, Montana, USA
June 1, 2007

Moved from Cimbicid Sawflies.

You're right, it looks like both of them. Do you know any way to tell them apart in the field?

can be moved to Trichiosoma triangulum page

Size for one....
Generally, Trichiosoma is 'much' larger, and lacks any metallic luster to the body. All Zaraea I have seen have been metallic to one degree or another.

Not so sure.
This looks much more like Trichiosoma triangulum to me.
