Silver Spotted Skipper Caterpillar

Green caterpillar
I am normally pretty good with bugs but graduated college before I had a chance to take the immatures course. There are about a dozen of these caterpillars that are bright green with brownish heads and small, bright orange eye spots encasing themselves on my false-indigo plant. I am assuming they are moths because they appear to be ready to spin cocoons, and not likely sphinx moths because there is no anal horn. Can you tell me what these might be and if they are possibly pests?

Hi Amy,
We are very thrilled to receive your great photo of a Silver Spotted Skipper Caterpillar, Epargyreus clarus.  You can get more information about the species on BugGuide.  Skippers are classified as butterflies, but many books, especially older books, consider them to be transitional between butterflies and moths in that they have characteristics of both.
