The color combination of black/white periodically turns up in nature. Generally speaking, it's an eye catching mix and rather exotic in appeal. Well known examples of this effect are Panda's, Zebra's, and of coarse Penguin's. Together, the two colors work as a play on light and shadows; breaking up a creatures appearance against the background of its surroundings. In effect helping it to blend in -- in plain view. Amongst insects (particularly butterflies) this color theme is also re-played. A number of our Swallowtail butterflies, some Milkweed butterflies (Idea), and of coarse a fair number of Pieridae butterflies exhibit this wonderful mix of color. Here, in the eastern United States the Zebra Swallowtail (Protographium marcellus) is our native "delight" on this play of color. It's distinctive wing shape and long tails make it easy to identify. The "tails" on this elegant beauty are 2-3 times the length of any swallowtail in the region. It's preferred food plant is Pawpaw. These are two examples, which I recently picked up in a Southern Illinois clover field. These are tough fellows to find in this condition when wild collecting them. Where I live I have to travel at least 3 hours just to potentially find them as they are not in my immediate area. These are rather fast flying butterflies with a somewhat erratic flight so, catching them on the wing is near impossible. Therefore, best to find yourself a clover field and wait for them to refuel where they can be captured far more easily as their attention is on pollinating. They do become damaged in no time after emergence so finding yourself good ones can be quite the challenge in it's own right...

Lovely specimens!
Just a note for everyone's info - Hestia Huebner, 1816 is a junior synonym of Idea Fabricius, 1807. It has been a very long time since I have seen anyone use it as the valid genus name for those giant Asian Danaiines.
Adam.

Oh' dear, I did indeed goof Adam! Indeed (Idea) has been in use for quite some time and I know this however, my mind just proposed the old genus name inexplicably and I kept on going... Thank you for being so observant and bringing it to my attention. I will correct that misnomer.

Another thing which I mean't to mention in my article was just how easily this species color breaks up its appearance in a field of flowers and other butterflies. I swear, when you see one you have to follow it literally to the flower its going to pollinate. If you take your eyes away from it briefly to spy anything else it simply "melds" into the background unseen until it takes off again.
It's not the same at all with other swallowtail species which seem to be easily found even if one looks away for say 10 or 15 seconds...
