Overwintering Black Swallowtail Chrysalis
Typically I find a couple of cats of BS on my parsley each summer and raise and release them with my kids. This summer we did not find any.....up until a few days ago (I am in NJ). Will this cat emerge from its chrysalis before winter or will it, as I assume, overwinter in the chrysalis?
If the latter, what is the best way to keep it over winter? Thanks!
