Tenthredininae, Macrophya bifasciata. Very nice pictures of this species. Occurs in eastern N. Amer. west to Tex., Okla. The host plant is unknown. I would be interested in knowing the plant in the picture. It appears to be ovipositing in the picture; if so, this would be the first record for a possible host.

 
Thanks, Dave
Thanks, Dave, for the ID and comments.

This was found on an Apple mint (Mentha sp.) leaf.
I thought it looked like it might be ovipositing, but not until I looked at the photo, so I never examined the leaf. I'm adding another photo that looks like ovipositing on another leaf.
Also it is on a leaf that has damage common to some mints caused by a black and red small bug. I don't know the name but see it frequently on damaged leaves. Is this sawfly parasitic, could there be a connection?

Lynn - Thank you
for the name of the plant. No sawflies have been recorded on Mentha in N. Amer., amd perhaps this will be the first one. It sure looks like it is ovipositing, and thus it could be the first record of the host plant for the larvae. If you ever find sawfly larvae feeding on this, make a record of it and let me know. I doubt there is any connection between the black and red bug and the sawfly; sawflies are not parasitic.
