Spangle Butterfly
Papilio protenorAlso known as Spangle
Spangle butterflies glide through tropical and subtropical forest corridors on broad, velvety dark wings adorned with shimmering blue-green scales. Males frequently gather along riverbanks to sip mineral-rich moisture, while females search canopy edges for wild citrus trees on which to lay eggs. Caterpillars rely on chemical defenses derived from their host plants, extruding a foul-smelling osmeterium organ when threatened.
