I had six caterpillars on my milkweed and I put two in a jar with some milkweed and brought it in my breezeway. Both formed a chrysalis, one a few days before the other. After about ten days, one butterfly emerged.
The first one came out of the chrysalis yesterday about 4:30 pm. The wing pattern showed that it was a girl!
As shadows fell, she was still clumsy so I made her a room for the night.
The second butterfly was a girl too. She came out at 9 am Wednesday and by noon was flying around the yard. This video shows her taking her first drink of nectar.
