Lafontaine & Schmidt (2010) listed two species of the genus Colocasia in America north of Mexico. (1)

Hampson (1913) listed a wingspan of 42 mm.

Wagner (2010) reported the larvae mature to 35 mm. (2)

Colocasia flavicornis can be distinguished from C. propinquilinea by the dark coloration in the median area of the forewing. In flavicornis, with wings folded in resting position, a bar can be noticed joining the am and pm lines across the median area. This is absent in propinquilinea. Also, the median area of propinquilinea remains relatively constant in color/shade all the way to the costa, whereas in flavicornis the median area becomes much lighter in color/shade about halfway to the costa, just before where the orbicular spot is located.

Crumb (1956) described the larva. (3)

North America, east of the Rockies. (4)

Holotype from New Jersey, in USNM. (5)

Deciduous woodlands.

The main flight period appears to be March to September. (6)

The larvae feed on a variety of deciduous trees including beech, oak, maple and elm.

Crumb (1956) reported Carya ovata (hickory). (3)

Wagner (2010) reported at least two generations with mature caterpillars from May to October. (2)
