From the time a Monarch Butterfly lays an egg on the host plant, Milkweed, it takes 10-14 days before the Caterpillar starts looking for the perfect spot to spin White "Silken Thread."
These Caterpillars crawled all around this Butterfly Cage for hours before finding the perfect spot. Can you see the 'Silken Thread'? (The one Chrysalis you see hanging formed yesterday from the photo I posted)
After spinning the thread into a little pile-it turns around and attaches it's rear to the Silken "Pile". Two by two it's feet detach and swings into the "J" position.
Third Stage- Pupa--Greek word means "doll". Which denotes a sleeping baby wrapped in swaddling clothes. More common term Chrysalis. 12 - 24 hours after the "J" position--changes slightly in color to bluish green and the antennae become limp. The caterpillar becomes limp and straightens. You can see the caterpillar move and expand inside of the skin. His skin splits on the back from the bottom and a shiny green Chrysalis is unveiled. The skin shrivels to the top. You can watch the Chrysalis dance and shake until the skin on top falls off. The black stuff on top is the skin. It was moving in this photo.
The shiny green Chrysalis with yellow bands changes appearance over the first hour or two. Shape will also change slightly. Yellow bands disappear and becomes a soft green color.
