Index of Subjects Hi Angus Here is an Isabella Tiger Moth I photographed in mid-July of this year in E Dalhousie, Kings Co. So best keep searching for one beyond May/early June 2015. Perhaps not all Pyrrharctia isabella caterpillars overwinter at the same stage? This was the first and only one of these moths I have ever seen and I saw no more of them this summer: https://www.flickr.com/photos/92981528@N08/14662009166/ But the number of images on BugGuide suggest they are very common moths, somewhere.

On our property without any searching there were 20 or more each day into early November when they started to lessen. Surprisingly there was little predation that I could find. Since they seem to prefer to travel across open areas one wonders how they escape predators. The dead ones had their interiors sucked out so likely the victims of crab spiders, although there are less likely suspects. > > Wooly Bears are the larval stage of the Isabella Tiger Moth. I have never found this moth. According to the literature. Wooly Bears overwinter as "near adult" caterpillars which, I presume, means their last instar stage so that in May/early June(??), 2015, there should be plenty of Isabella Tiger Moths around. I hope to find one! > Angus > >
