I have a lot of flowers and have cut a few to enjoy. I have noticed some very tiny little inchworm like worms popping in and out of the center of some of the flowers. What are they? Do I need to worry about them being in my house or worse am I disturbing a species that needs help and thought it was safe in my garden? They seem to be in the black eyed Susan's and zinnias but lately I spotted some on the coreopsis.
