Is this a dark form Tiger Swallowtail?
This dark..uh..I don't know, keeps flitting into the yard. S/he keeps flitting in though, with a yellow Tiger Swallowtail, making me think it's a dark form Tiger Swallowtail? Today was the first time I have ever been able to get a photo of it! They twirled together, then separated and went to different Eupatoriums to drink from, so I couldn't get a picture of them together. Only separate. Here they are
the dark one
And the yellow Tiger Swallowtail
