Moved from "Symphyta" - Sawflies, Horntails, and Wood Wasps.
Interesting! Sorry to say I didn't collect it. I'll keep an eye out for others next time I visit that spot. These are the only photos I got of it, but if there is an area in any of these shots you'd like me to zoom in on I can add a closer crop.

Tenthredinidae, Selandriinae
This is an odd, and perhaps very rare, thing! I need to check it out with the collection and get back to you later.

 
Found it!
Adelesta nova (Norton, 1867). A rarely seen sawfly. Norton described it from a single specimen from "Maine". I have seen only several additional specimens from Quebec, New Brunswick, and Nova Scotia. No one knows is host plant or anything else about it. Nice find!

 
Thanks for tracking it down!
There are a great many host plants to choose from in this spot. I visit it often, and I will make a point of looking for larvae there.
