Monarch chrysalis on butterflyweed
A monarch butterfly chrysalis, hanging from a butterflyweed stem. This caterpillar was about 2 inches/6 cm in length. The chrysalis is quite a bit smaller, 3/4 of an inch/2 cm in length. A photo of the yellow and black striped caterpillar this chrysalis used to be is here.
Here's a photo of an adult monarch, on a plant of the same type. Like all butterflies, monarchs have complete metamorphosis, from egg to caterpillar to chrysalis to adult, if all goes well.
Here's a photo of the same chrysalis, in which you can see the new monarch inside.
I am glad to be curator of an "Arthropod Eggs and Pupae" gallery, made up of photos by other people.
Butterflyweed is a member of the milkweed family, which family is the food of these butterflies, and other insects. See here for more about monarchs, Danaus plexippus.
You can see butterflyweed flowers, and learn a little more about this particular plant, here. The scientific name of the plant is Asclepias tuberosa.
On October 2, I added this to The Top 30 Green group. I don't think it made the cut, or it got cut out shortly after being added. I can try again on November 3rd, 2008
