Luna, the butterfly is a tiger swallowtail/eastern tiger swallowtail, <i>Papilio glaucous</i>. Goose, the black swallowtails you're seeing may be "dark form" females for the ETS (some females are also yellow). They may also be completely different species, as well. Also, there's a genus in the swallowtail family, <i>Parnassius</i>, without a tail, and looks nothing like your standard swallowtail with clear wing sections and bright pink eyespots. It's kind of funny for me how these topics turn up in clumps, as just last Sunday I found a swallowtail caterpiller on a willow leaf during a memorial walk for a neighbor along the Nisqually Delta park. Here are websites for the ETS and Zebras for a comparison:

Not too sure about the dragonflies, since I'm only familiar with the northwest species. My best guess at the orange and black one is a brown-spotted yellow-wing, but the pattern looks off to me, so I'm guessing a closely-related species. Can't tell on the side-by-side ones, need a shot from the vertical.
The field doesn't get into subgenus much with insects, usually if it's newly discovered and/or they haven't really figured out how to place it, yet. Usually, once you drop below family (LOTS of subfamilies), it's genus (<i>Papilio</i>) and then the species name, which is genus + species (<i>Papilio glaucous</i>. Hope you're all taking notes, there'll be a quiz after the thread.
