Sawfly - Tenthredo ornaticeps

Thanks John
for all the sawfly id's. You've cleaned up a bunch of them in this group!

Tenthredo ornaticeps
I'm not 100% certain of the ID, but it looks just like it

Tenthredo sp. - (Tenthredinidae)
Web-spinning sawflies (Pamphilidae) have much thinner, many-segmented, and most often distinctly longer, antennae. Shape of the abdominal apex suggests a male of this wasp-like species.

I agree.
Note the blocky head, too. Pamphilidae have heads that are VERY round.

Thanks for the correction.
