So Jack is hiding all the Monarchs. Now we know.
I think your Sulphur is a Southern Dogface but my books are packed in the car so I can't be certain. Someone help me out. And your Swallowtail appears to be a Red-Spotted Purple. Darn all you guys with your Red-Spotted Purples! Tormenting me with their beauty! But maybe that means the timing is right and I'll see on on this trip. FYI, the RSP is a cousin to the Viceroy. Both are in the Admiral family. The Viceroy is well-known for mimicking the Monarch, but the RSP mimics the Pipevine Swallowtail. They're lookalikes! Hey, if it keeps you from getting eaten, I say go for it!
