Overwintering butterfly pupae
I live in NE Ohio and I have some PVS pupae that should overwinter. A few of the pupae are greenish colored and I have heard that sometimes these will eclose in the fall. Is it okay to leave all of the pupae in a cool room (in the 60's) for three weeks or so to be sure they're not going to eclose until next spring? I store them in a plastic container in the fridge over the winter. Also, does anyone have any tips for storing them in the fridge or outside? Earlier this year when I took some other pupae out of the fridge, most of them didn't and still haven't eclosed. Did disease cause this? Any ideas would be appreciated. Thanks.
