A Risk Of Being A Straggler
This late season chrysalis was formed on 06OCT22. The monarch butterfly may emerge as early as Sunday, 16OCT22 (10 days is within normal range) and I usually release them on the same day they emerge. With three days of cold temperatures (27-55° F.) after the 16th, I'll have to decide whether to release it (and hope it can beat the low probability of survival) or let it live its short life in captivity with the comfortable of containerized tropical milkweed plants and warm indoor temperature.
