Index of Subjects I was wondering how the moths make the sounds you mentioned. I did not find out the mechanism but did come across this article suggesting how the Tiger Moths may use these sounds to deter predators: http://scienceblogs.com/neurophilosophy/2009/07/17/tiger-moths-jam-bat-sonar/ Must keep an ear out for this next season.

I suspect like baby seal turtles, the larvae are heavily predated and parasitized during their fall wanderings. If you find a moth, pick it up and hold it near your ear.

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
