RUDDY DAGGERWING

Another new pretty one, shown flitting about male flowers of a Croton, is shown above.

Bea identifies this one as the Ruddy Daggerwing, MARPESIA PETREUS, a member of the enormous Brush-footed Butterfly Family, the Nymphalidae, and in the same subfamily as North America's well-known Admirals.

Ruddy Daggerwings are fair-sized butterflies, about three inches across (9 cm), orangish on top, and mottled brown and black below, camouflaged as a dead leaf. Their caterpillars feed on fig trees, which are common here.

Ruddy Daggerwings are found in tropical lowlands forests and edges from the US/Mexico border (some strays as far north as Nebraska) through Mexico and Central America to Brazil.
