Hi there, I’m hoping you can help me. I found this bug, dead on my deck yesterday. I have never seen one before and cannot find anything similar online. I took a few pictures and am really hoping you can identify it for me.
Thank you!

Elm Sawfly

Hi Jenifer,
This impressive insect is an Elm Sawfly,
Cimbex americana, and it is a non-stinging relative of wasps and bees.  The larvae of the Elm Sawfly feeds on leaves and is often mistaken for a caterpillar.
