American Dagger Moth caterpillar

Asked September 16, 2014, 5:41 PM EDT

I live in Castle Rock, this afternoon I saw two of the American Dagger Moth caterpillars in my back yard. I went to several web sites to see if there was any reason to be concerned with these critters.

This species feeds on a number of different trees and shrubs, but their populations are rarely high enough to cause any significant injury.
