It sure would be interesting to leave them outside under natural conditions and see if they make it. I don't know what their tolerance is. Can you take some photos and post the record to BAMONA?
The Montpelier Giant Swallowtail caterpillars (or at least two of them) have formed chrysali (is that the plural?). We're holding them at the North Branch Nature Center on the off-chance that they emerge next spring. I was thinking of storing them in the basement near a bulkhead door so they stay cool, but above freezing for the winter. Unfortunately, they were discovered accidentally by the homeowners while they were doing yard work and may have been inadvertently damaged. They were found earlier this week.
