K'aalógii is the Navajo word for butterfly.

Here's an interesting insight: k'aalógii was, traditionally, one of the first Navajo constellations, carried and set into the sky before Coyote scattered the rest of the stars by flinging them upwards.

Moved from Eastern Tiger Swallowtail.

I thought it might be a blooper. Anyway, the differences are subtle, but they are there. Yours and the California one definitely look different from the eastern one to me, but the differences are indeed subtle. The wings are bigger (compared to the body) and somewhat broader, slightly more rounded on the eastern. The dark stripes tend to be slightly narrower and placed slightly differently on the eastern, and so on. On P. rutulus (and canadensis), but not so much on P. glaucus, there is usually a characteristic bend in the inner edge of the dark margin on the front wings. Also, on the females (which are what in the photos here), notice the blue on the front wing of the Eastern (common on Easterns, not on Westerns). There is a spot on the hind wing (upper/outer angle) that is usually orange on Easterns, but yellow on Westerns (hidden in these pictures), and so on. The undersides show more concrete differences. Also, Easterns tend to be considerably larger. However, no matter how you look at them, they are very similar, and can be confusing (and not two look exactly the same - there is plenty of individual variation). I learned them first as a boy in Eastern Colorado, and I could tell them apart in flight (usually), but that was with lots of practice (they behave a bit differently too, which helps). If you want to see more related types, look at the Mexican, Canadian, and Appalachian Tigers. They are all very very close, especially to P. rutulus, in appearance. Many photos get mislabeled and show up with the wrong names on the internet, and even in books. Particularly true when the photos are from areas where two or more come together.

This is one of my favorite groups of butterflies, in fact one of my favorite groups of anything!

This is indeed a female, but it is Papilio rutulus, not P. glaucus. P. glaucus is found in Colorado, but only east from the mountains, not on the Western Slope. The shape of the wings and the markings are typical of P. rutulus on this one.

is a good indicator or a female. Her forewings are slightly more rounded than the male, but the best indicator is the shape of the "plump" and "full" abdomen. Many females will have much more blue. Pic is slightly overexposed or she is a paler specimen. Nice picture. Farther west, is the Papilio rutulus, Western Tiger Swallowtail. Check out its range.
