White worm/caterpillar eating my shrubs

Asked July 18, 2018, 6:13 PM EDT

This white worm is eating all the leaves off two of my shrubs. As you can see in one picture the white catapillar sheds and becomes green and yellow. And when you touch the white worms it leaves a white powder on your skin. Would vinegar work to get rid of the? I don't want to use anything that will kill Monarchs or other butterflies.

Hi, I think that is a dogwood sawfly. https://hortnews.extension.iastate.edu/2009/8-12/sawfly.html

They only feed on dogwood. It is best to hand remove them and destroy. Since they are only dogwoods and monarchs are on the milkweed, you should not have any problems.
