DISTRIBUTION:

Eumorpha phorbas (wingspan 112-121 mm) flies in Suriname and in
Mexico;
Belize: Cayo;
Guatemala: Izabal (JM);
Nicaragua: Zelaya, Rio San Juan;
Costa Rica: Guanacaste, Puntarenas, Heredia, Limon, San Jose, Alajuela.

I suspect there are populations in the other Central American countries.

In South America it is confirmed in
Colombia: Isla Gorgona;
Venezuela: (Bolivar (JRAC);
Suriname;
French Guiana: Kaw (AU);
Peru: Junin: Shima, probably throughout eastern Peru;
Ecuador: Orellana, probably throughout eastern Ecuador; and
Bolivia: La Paz, Santa Cruz. I suspect it is also in Venezuela (now confirmed (JRAC)), Guyana, eastern Columbia and northwestern Brazil.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Eumorpha phorbas broods continuously with adults on the wing every month of the year in Costa Rica and along the west coast of South America as far south as Bolivia. Andres Urbas confirms a March 31, April 1-8, 2011, flight near Kaw, French Guiana.

Adults nectar at various flowers. Eumorpha phorbas larvae probably feed upon grapes (Vitaceae), dogbane (Apocynaceae), or evening primrose (Onagraceae) families.

ECLOSION, SCENTING AND MATING:

Pupae wiggle to surface just prior to eclosion. Females call at night, and males (below) fly into the wind to pick up and track the pheromone plume.
