I was fascinated to find these monarch butterfly chrysalis’s hanging out on an agave in the crevice garden recently. Our entomologist, Bill Reynolds, tells me that when the caterpillars are finished feeding, they will often migrate from a nearby asclepias to all kinds of odd plants to hangout until it’s time to come out of their closet. It’s hard to imagine a full-size monarch butterfly inside these little structures, but perhaps they are like Dr. Who’s Tardis.
