The uphill climb

This was such a tiny caterpillar-like larva, I don't know how I ever happened to notice it, lol! It was clinging to a thin grass stalk and appeared as just the slightest thickening on the stalk. Needless to say, this is a macro! And it's the only photo of this insect that came out - the rest have been deleted : ) So glad I decided to check it out just in case it was something. Wonder if this is some kind of Sawfly larva? Photographed at the Medicine River WIldlife Centre on a wonderful botanizing day yesterday.
