Coordinator notes: This is the Two-tailed Tiger Swallowtail with narrower black stripes on the wings. Obviously of the successive flight in summer with wider black borders on both sets of wings yet retaining the narrower stripes characteristics to the early flight in May and June (known as form pusillus). Some in the late flight have wider "tiger" stripes than this one does. Nice photo. Mike
