Butterfly sighting

Location: Fitchburg residential butterfly garden
Dane County

On each of the past three days I have found a BST cat on the rue in our garden, one of them a rather early instar. Because of the late season, I've brought them in to finish feeding on cuttings under the warmth of a tensor lamp. When they form a chrysalis they will go out to the screen porch to chill for the winter.
