Observation notes: Found this caterpillar on a concrete pathway in a built up area not far from downtown Albany, NY. Temperature was around 41 degrees and the day was mostly sunny. The caterpillar was curled on the path in the same manner as it is in the image. It didn't move in the time that I saw it.
The nearest natural habitat is a thin green belt along a railroad bed nearby, enough habitat to support resident Downy Woodpeckers, breeding Common Grackles and other bird species. The trees along the railway include lots of sumac(sp?) and Box Elder as well as some Hackberry and other shrubs I'm unfamiliar with.
I found the same species of caterpillar at approximately the same spot a couple of weeks earlier though that one was paler and browner, possibly a younger caterpillar from the same brood?
