Golden-rod Pug - caterpillar

I have only rarely taken the adult Golden-rod Pug moth but the caterpillar is quite common on the food plant according to Brian Statham who took this caterpillar on the roadside by Flash Dam above Matlock. There are a number of moth families where the moth is easier to locate as a caterpillar than as the adult moth and many of the pugs fall in to this category. It's also a good aid to identification where the adults can be difficult to distinguish.
