I recall the LB's of old hibernating, we used to see then gather inside the cabins and sometimes in the house in the fall and then reappear in the spring. This past year I've seen them in my mothers house all winter as well as now. I've been working in some temp trailers in Pelham and they've been there all winter as well. It's only now that I'm seeing them go away. Perhaps they are leaving to go outside, which is a good thing for all concerned. I was just about to set up a laser based bug fry'n'die.
