hi everybody. I've got a question for you. Is there a point at which the night time low temperatures become too low for caterpillars? I have a pretty good size black swallowtail cat on the fennel & would prefer to just let it be but our nights are getting pretty cold; low 40s and upper 30s. Then, there are some real small ones on the parsley too. The caterpillars are definitely in torpor first thing in the morning but as soon as the sun hits them they start getting active.
