Is our black swallowtail caterpillar dead?
Our black swallowtail caterpillar crawled to the top of it's container, attached itself to the top and has been hanging there for 2 days. Actually, this will be day 3. I'm wondering if it's dead. Do they hang that long before pupating?
If it is attached normally with a "thread" around its middle it might still pupate. My last black swallowtail caterpillars took a few days to shed their skin and pupate.
