Observation notes: We are at an altitude of 8,100'.The weather is clear with night to day temperature ranges between 40F and 75F. The caterpillars have been around for a week now and are busy eating the leaves. There are hundreds of the caterpillars around our house on the same plant. I think the plant is a currant but not positive.
