Description

Question Mark Butterfly (Polygonia interrogationis) in my back yard. This is the umbrosa form, with the hindwing darkened instead of orange. The row of 4 spots (3 circles, 1 oval) distinguishes this from the Eastern Comma Butterfly (Polygonia comma), which has 3 spots in that row. The actual question mark that gives this species its name is on the underside of the wing (as is the comma on its cousin).
