  1. Looks like a cimbicid sawfly. Probably Trichiosoma sp., possibly Trichiosoma triangulum. A good clue that it’s not a wasp is the clubbed antennae. Posted 11 days ago
    1. And, my guess would be that this is a male because females are usually a bit chubbier. Posted 11 days ago
    2. Looks good to me too. Posted 11 days ago

The Cimbicid Sawflies are large robust sawflies with clubbed antennae. They feed on the foliage of trees and shrubs.
