The first one is a Silver Spotted Skipper. Nice catch, you don't normally see them with the wings open. The second one is indeed a Hackberry Emperor.

Thank you. I just looked at some images of Kalanchoe blossfeldiana, and while the scalloped leaves are right, I'm pretty sure that isn't the exact plant. Here's another picture, this is the one that I had to decapitate because it became too top-heavy and fell over. You can see the little stalk at the side, which in this case was bent when it collapsed.

That looks like Pastinaca sativa, Wild Parsnip, to me. Here is a link that might be useful: Google image results

These are both neonate (hatchling) snakes which can have patterns very different from the adults. This one looks to me like it might be a baby Calico Snake (Oxyrhopus petolarius). The head shape and pattern are pretty close for that species. I have attached a photo of an adult from Chiapas, Mexico for comparison.
