It's a silver-spotted skipper, one of the prettier ones. They use a variety of members of the pea family as host plants. I made this picture several years ago - it's hard to get a full bodied picture of one, so you did a good job of getting your picture!

It's a Silver-spotted Skipper.
I've never heard of skippers using beans or Apios - you taught me something.

I've heard of them using beans, primarily the red flowering ornamental bean, Scarlet Runner Bean. It may not be their first choice, depending on where you're located and the availability of food sources.

Congrats, Tracy! I keep checking the neighbors wisteria which is also a host plant for SSS's. I think those cats are adorable.

I see the butterflies all the time but don't see many cats. When I do they are usually on the soybeans. This is the first time I've seen any type of cat on my Apios. Sherry will the chrysalis winter over or will it emerge this fall?
Thanks

I don't know, all butterflies and some moths are unpredictable in that respect. I'm guessing that in Maryland, this one will overwinter. They supposedly overwinter in leaf litter on the ground, so it's a wonder they're so common - the pupal shell must be thick.
