Barred Sulphur Female
caterpillar was found munching on the yellow flowers of a Cassia Tree.
I believe it was a Christmas Senna Cassia.
This one had the dark bars on its back like two stripes.
Also notice the pointy spines.
On 10/29/10 she emerged.
very difficult to get a good picture with the wings folded down.
No butterflies were hurt during this picture!
The female Orange Barred Sulphur does not have the orange bar on the forewing like the male.
