When a Monarch caterpillar is about to pupate, it spins a button of silk onto a twig, attaches itself by its rear feet, and hangs in this classic "J" posture. In 24-hours, this caterpillar will molt for the last time, revealing itself in a new life-stage as a chrysalis.
Photographed at the Fullerton Botanic Garden, Cal State Fullerton.
Hand-held Nikon D5000 at ISO 400, with Nikkor 105G macro lens, 1/200-sec at f/16, open shade & Nikon SB-600 speedlight with O-Flash 3/4-circle Fresnel prism attachment.
Detail is great in the download. I'm curious about the make-up of the material they use to attach themselves. Is this the same as spider web stuff? Not very scientific-- but you see where I'm going....

Most butterfly species spin a bit of silk for chrysalis anchoring purposes, and many moths spin complete silk cocoons to protect & hide their chrysalis. The silk moth family is the most famous, as an entire industry is built around unwinding, retrieving, and weaving their raw silk into cloth and garments.
Notice that this caterpillar
missed placing its feet properly onto the silk button. It is grasping just a few strands of silk on the twig. This became apparent the next day, when I found on the ground, the soft chrysalis and molted skin. While shifting its feet to drop the molted skin, the chrysalis lost grip on the few silk threads.
I looped dental floss to the feet of chrysalis, and hung it in a small butterfly cage, now in my warmer kitchen. We shall see if the chrysalis survives to eclose as a mature butterfly.
so cool - great shots and info.
very nice shot,can't wait till warmer weather get here so the bugs will come out.Bill

Just south of fort worth,he looks harder than I do I guess.Bill
I think Tom and Martin (f/stop22) put us all to shame in the "looking" department.

I purposefully choose my settings to properly capture background exposure, which is ISO 400, 1/200-sec at f/16. I adjust my speedlight illumination source to properly expose my subject at same time.
