Overwintering Papilio chyrsalises
Anybody else overwintering Swallowtail chrysalises this winter? Or in the past? I have 10 chrysalises overwintering this year - 3 BSTs (P. polyxenes), 7 SBSTs (P. troilus).
Last year I attempted to overwinter 2 BSTs in an aquarium tank in the garage, but they died by Spring. Looked like the chrysalises rotted. After discussion with Miss Sherry about them, I think I probably spritzed them too much and they didn't get enough air circulation.
This year I've put them in a mesh sleeve and hung them on the back side of the house. I think they are inaccessible to predators in this location and they get a small amount of sun and rain exposure and good air circulation. I hope this works. Any comments welcome!
