“Actually, the butterflies donâÂÂt, âÂÂcome back.â These butterflies have never been to Pacific Grove. They are the great grandchildren of the butterflies that left last spring.*
Indeed. You are correct. Excellent observation. If memory serves me correctly, butterflies typically live between 2 - 4 weeks after emerging from their cocoon. Just long enough to eat, fatten up, mate and then lay eggs.
It’s amazing.
