caterpillars on red twig dogwood

Asked August 14, 2020, 7:01 AM EDT

I've started to see these caterpillars eating my red twig dogwoods. I counted close to 20 on one plant.

This is dogwood sawfly larvae. It will eat a significant amount of foliage, so it can be worthwhile sometimes to take steps to control it, particularly on a small or young plant.

Here is our webpage that includes what they will look like as they mature (actually pretty cool): https://extension.umd.edu/hgic/topics/dogwood-insect-pests-identification-and-management#sawfly

Manual removal is easiest. If you miss a few, it's not a big deal. They show up some years and not others.
