Elm Sawfly

Dear Veronica.
This is not a Western Cicada Killer.  It is a non-stinging Elm Sawfly.

Thank you Daniel. We dont have Elm trees here though!

Hi again Veronica,
According to BugGuide:  “hosts include elm (
Ulmus), maple (Acer), birch (Betula), willow (Salix), and basswood (Tilia); adults girdle bark on twigs.”  Additionally, lists of host plants are often incomplete and many species adapt to different host plants due to garden cultivation and species range expansion.
