Insects confuse me, there's so many species. I've searched for this one but have come up empty so far. There are a dozen (at least that I can find) crawling around on my 1 year old hops. At first glance I thought it was a caterpillar but then noticed the six legs. I'm in northern Wisconsin, and while we've been having some 80+ degree temperatures in the daytime, we keep edging closer to frost at night. I'm a little worried they're finding a host to bed down next to for the winter.

The picture shows the line-ruled paper, so it's a small bug(ger). Good? Bad? Anyone shed some more light on it? Thanks!
