This species has been abundant this year, first as the adult (moth) and now as the larvae. I rarely see the moths and have seen the larvae only a handful of times, so to suddenly see so many moths and now, caterpillars, is quite amazing. Most insects have peaks and lows in their populations, and this is clearly a peak year for them. They are on wild grape which is abundant along this particular trail, almost every 4th or 5th tree is draped with masses of the vine.
