Tenthredinidae, Heterarthrinae
Fenusa sp. The three species in this genus are difficult to separate from photos. They are leafminers of alder, birch, elm.

 
Good to know...
I don't have any of those trees so maybe it's just visiting. Thanks!

Sawfly of some sort.
I won't venture to go further. I'm sure others will be able to tell you more.

 
Thanks, Ken.
I'm guessing that a sawfly is not a beneficial insect. Thanks for the ID.
