There were two of these beauties - Twin-spotted Sphinx Moth (Smerinthus jamaicensis).
I love how the body of the moth is arched in a sort of S-shape as if it were designed to have a little rider on its back!
This is the Yellow Slant Line Moth (Tetracis crocallata). It was sitting on my propane tank, taking a rest. A rather uninspired name choice for its common name, but it does make it easy to identify.
Here's an interesting moth that sort of looks like a curled up dead leaf. It goes by the name of Sigmoid Prominent (Clostera albosigma), but if you like, call it the curled up dead leaf moth. If you look closely, you'll see that there's another moth disguising itself against the wood in the picture below. It's some kind of geometrid moth but I'm not sure what species. There are over 1,200 geometrid species native to North America, and I don't have the time to positively ID this one!
Just above this moth was another interesting species - the Modest Furcula moth (Furcula modesta). It is also quite easy to spot because of its distinct black markings.
Finally, another moth vying for the prize of looking like a dead leaf. This one is the American Lappet Moth (Phyllodesma americana). It reminds me, a little bit, of a furry hedgehog with wings.
