Help identifying please

Asked February 18, 2019, 1:09 PM EST

I had an infestation last year on my dotted loosestrife. I have been unable to figure out what it is. I sent a message to the MSU website but they were unsure of what it was and sent me a link to the Missouri Botanical Garden. I'm not seeing the specific caterpillar on the website.

Last season I tried Neem and diatomaceous earth neither one seemed to help for more than a day or two. I have 30 of these plants in my yard so its little more large scale than picking them off :)

I attached some pictures if that helps.

Thank you so much!

That is a sawfly larva, probably Monostegia abdominalis (Hymenoptera: Tenthredinidae).
