Cloudless Sulphur Phoebis sennae at Kiptopeke State Park, VA

NOGALITO, JALISCO, MEXICO

In northern Champaign County near Sangamon River, IL, USA

Female Cloudless Sulphur (Phoebis sennae) butterfly at the Faulkner-Franke Railroad Prairie Reserve, Illinois. She wouldn't let me get very close and I didn't have my macro with me. Finally shot it on partridge pea (Chamaechrista fasciculata).

This is the yellow form of the Cloudless Sulphur caterpillar. The color of this larva depends upon which part of the Senna plant that it eats. When eating the leaves the caterpillars are green. If they eat the flowers then they are yellow like this one.

Phoebis sennae eubule (Linnaeus)

(Lepidoptera: Pieridae).

Cutler Bay, FL

Well, actually, it's a gardenia bush.

Whenever I hear someone say "Yuck!" about a caterpillar. I sigh and smile because I know this is the goal of the caterpillar. Glorious, isn't it? Phoebis sennae My garden. Houston, Texas. May 2008.

Butterflies is the theme of my company's calendar this year. Definitely not easy to shoot since the butterflies decline to stay still.

This is what winter is usually like here. We're finally getting the right weather
