Vernon A. Brou has indicated images depicted are not true falcifera. See the discussion on Callionima parce page. I have moved some images and now believe that all images on this page are C. falcifera, based on information from CATE and personal communication with Jean Haxaire.

DISTRIBUTION:

Callionima falcifera (wingspan 68-73 mm) flies in
Mexico;
Belize: Corozol, Orange Walk, Cayo, Toledo;
Nicaragua: Madriz, Jinotega, Matagalpa, Chinandega, Managua, Masaya, Granada, Isla de Ometepe, Rio San Juan;
Costa Rica: Puntarenas, Guanacaste, Alajuela, Lemon, San Jose, Heredia;
Jamaica (ssp elainae), etc., south through northern South America (northwestern and eastern Venezuela: Aragua, Barinas, Bolivar, Carabobo, Falcon, Portuguesa, Trujill, Zulia), possibly to Paraguay: Concepcion; Amambay.

Hemeroplanes elainae Neidhoefer, 1966, Jamaica, is a synonym for Callionima falcifera

"Forewing apex acutely pointed, falcate (although the degree is variable).

"Forewing upperside extremely similar to Callionima parce; consistently differing only in the pale oblique apical line expanding at M1 into a pale patch that does not curve back up the outer edge of the apical line towards the apex but is directed posteriorly towards the outer margin, resulting in the area between the outer margin and the apical line being the same colour as the area immediately basal to the apical line."

FLIGHT TIMES:

Callionima falcifera adults fly continuously and specimens have been taken in every month in Costa Rica.

This species is redder, has more falcate wings and flies after midnight. The very similar Callionima parce is browner, slightly less falcate and flies before midnight.

ECLOSION:

Adults eclose from pupae formed in flimsy cocoons among leaf litter.

SCENTING AND MATING:

Females call in the males with a pheromone released from a gland at the tip of the abdomen. Both males and females come in to lights, but males are taken much more frequently that way.

EGGS, LARVAE, PUPAE:

Larvae feed on Stemmadenia obovata and probably on other members of the Apocynaceae family. Huevos de caballo, cojones de burro, cojón, cojón de puerco, and cojón de coche (Guatemala), are the common names for Stemmadenia obovata. In English, the common name is "Horse Testicles". This tree has a smooth, pale whitish bark with prominent lenticils. The leaves are simple and glossy. The fruit is green and is paired (resembling its common name "horse testicles").

The narrow, flattened head of the larva is clearly visible in the lateral and dorsal views below.

Larvae are frequently parasitized by Drino piceiventris, one of the Tachinidae.

Note the very hooked forewing tips on original Callionima falcifera .
