Which beneficial insects work on sawfly larvae?

I want to finally beat the scourge that is sawfly larvae. Are there any predatory insects I can get that will destroy these buggers? I’ve searched through various websites and I don’t see anything listed as feeding on sawfly larvae, just Lepidoptera caterpillars, which these aren’t.

I have emailed the Bug Lady, she is the authority on the topic of beneficial insects. Waiting on her response.

Thank you, Rosejoy. Any word from the esteemed Bug Lady?

She has never emailed me back. Maybe Diane Sommer can contact her. Sawflies are a big problem.
