Day 6 is yet another diurnal moth, a buck moth (Hemileuca sp., likely H. nevadensis, Hodges#7731, as there were larvae feeding on willows). Buck moths are in the silkworm moth family (Saturniidae), and while not quite a spectacular as many of their relatives, are still quite showy. The caterpillars have urticating spines -- they sting, although the punch varies by species.
The University of Wisconsin-Milwaukee has a nice post about the possible origin of the name "buck moth" and the taxonomy morass that occurs in here in the upper Midwest.
