A nearby place(my old neighborhood, actually) has an infestation of tiny green catepillars. The are 1/4-1/2", I would guess and hairless, aka like inch-worms. They are not the web-building type and they are so numerous, you can hear them munching on the leaves of the tree and they fall out and crawl around on the ground. Does anyone know what they are and if cooled to lethergy, will they make good cp food? I would guess being leaf-munchers, you are taking a risk no matter what.
