Pipevine Swallowtail on teasel

Pipevine Swallowtail

I chose this image because it caught the iridescent blue of the underside of the hindwing on the Pipevine Swallowtail. I see these butterflies often locally; pipe vines themselves, the host plant for this butterfly, I’m not positive I have ever noticed. They must be nearby somewhere. This image taken with a Nikkor 70-300mm AF-S ED VR. I find a good telephoto lens to be invaluable with butterfly photography. The plant the butterfly is feeding on is a teasel. This plant is not native to America, but the butterflies do not care; it readily attracts swallowtails of various kinds.
