Most of these pics are of the Giant Swallowtail Butterfly, of the species Heraclides cresphontes. This huge butterfly is black wit yellow spots in a distinctive diagonal pattern across the wings. On the rear wing, the Giant Swallowtail has a single protrusion with a yellow dot, giving the wing the characteristic swallow-like shape. The underside of the wing is mostly yellow, with a black pattern. I haven't been able to identify the black and white Swallowtail Butterfly. Its markings are similar to the Giant swallowtail, but the pattern is slightly different and the light spots are white rather than yellow.
