my plan was to perhaps put a baby by itself, count the moults until it was an adult, then find the varying sizes in my collection and preserve them in order. I'm not planning on a huge mass murder or anything, just trying to make something informative, and to me, neat. I've always loved the bug jewelry, and what i find out about resin casting will probably also be used to make some awesome roach jewelry. I guess I'd feel worse about killing them, but they suffer much worse deaths than being frozen by getting eaten alive by my lizards.
