Strawberry Sawfly (Claremontia confusa, #964)

I wondered what was shredding the leaves of alpine strawberry plants in a planter outside the front door. Turns out to be sawfly larvae from the Strawberry Sawfly (Claremontia confusa). The sawflies are supposed to fly in May-June and people report their strawberry plants being eaten in July, so maybe these are from a second generation.
