What cats are eating my Purple Coneflower?
I have caterpillars on my Purple Coneflower that I hope someone can identify. I haven't been able to find a reference that lists coneflower as a host. The cat pictured is 3/8" long. Several cats attack a single leaf at once. When they are done with it, the leaf is black and covered with frass. They also eat the bloom petals. They are quickly destroying the foliage. Can someone please tell me what they are?
