Harris Hawk. The Desert Museum near Tucson had a raptor demonstration while we were there. A Peregrine Falcon and Barn Owl were also on view, but too far away to get decent photos.

At Tohono Chul Park, a Queen butterfly, Danaus gilippus.
Black swallowtail (Papilio polyxenes), Tohono Chul Park.
We saw Desert (Asclepias linaria) and White Stem (A. albicans) Milkweed everywhere, on hikes in natural areas as well as in every botanic garden. Arizona had good summer rain this year, so flowers and butterflies were plentiful.

The lizards we saw in Arizona were larger and stouter than our own Western Fence and Alligator lizards. This one at Tohono Chul Park was at least double the size of what I see at home.
This one was on a wall at the Desert Museum:
