When I saw this in the Jordanelle dam wetlands in the Heber Valley area my first thought was "small wasp".

The larvae of these sawflies feed on alder, willow, and birch.

It was tough shooting these photos as the sawfly was trying to get away without actually leaving the tree.
 I got enough information for the experts at Bugguide.net to identify it as as adult Striped Alder Sawfly.
