Species: neglectum neglectum Rothschild & Jordan, 1903

DISTRIBUTION:

Aleuron neglectum neglectum, (wingspan 48-53 mm), flies in Peru (specimen type locality) and in
Mexico;
Belize: Cayo;
Guatemala (JM);
Costa Rica: Guanacaste, Heredia, Puntarenas; through
Central America and much of South America, including northern, central and
southern Venezuela: Amazonas, Aragua, Bolivar;
Trinidad: unconfirmed but might be present; to
Colombia: Mocao (possibly Mocoa in Putamayo); Meta: Villavicencio (GN)
Ecuador;

There are no pearly white lines across the base of the discal cell or across the first abdominal segment as there are with A. iphis.

Extremely similar to Aleuron iphis but most easily separated by the smaller, black (not brown) median patch on the underside of the forewing. Basal white belt of abdomen upperside much narrower than in Aleuron iphis, the following tergite not brown. Forewing upperside very similar to Aleuron iphis but differs in the black median lines indistinct posteriorly, except the basal most, which is bordered white basally but not distally, except at costal margin. Forewing underside with a smaller, black median patch (brown in Aleuron iphis) that generally does not touch the discal cell, least not between M3 and CuA1, there being always a spot of the ground-colour at the base of cell M3 - CuA1.

FLIGHT TIMES:

Aleuron neglectum neglectum adults fly at dusk and are not attracted to lights. They do visit puddles and frequently nectar at flowers of Duranta repens.

In French Guiana adults are on the wing in March, August and October. In Mato Grosso, Brazil flights have been observed in February and May.

Gregory Nielsen reports a July flight in Villavicencio, Meta, Colombia.

ECLOSION:

Adults eclose from pupae formed in shallow subterranean chambers.

SCENTING AND MATING:

Females call in the males with a pheromone released from a gland at the tip of the abdomen.

EGGS, LARVAE, PUPAE:

Larvae probably feed on Curatella americana and other members of Dilleniaceae family. Eurides Furtado reports them on Curatella, Doliocarpus, Davilla nitida and Tetracera.

The larvae have very long "horns" in the early instars and are green.

Larvae become darker, almost brown, as they mature and anal horn is greatly diminished.

Larval development takes about 36 days.

Eclosion is approximately 18 days after pupation. The pupae are smooth and shiny. Image courtesy of Eurides Furtado.
