Tenthredinidae, Allantinae
This is Monsoma pulveratum, an alder feeding sawfly. A European sawfly that was first found in N. Amer. in Newfoundland 10-15 years ago, and just the last few years in Alaska where is it quite a serious pest of alders. I've not seen this from anywhere else in N. Amer.

Monsoma pulveratum

Could you please move it to the species page?
