DISTRIBUTION:

The False-windowed Sphinx, Madoryx pseudothyreus (Wing span: 2 5/8 - 2 3/4 inches (6.6 - 7 cm)), flies in tropical climates: The West Indies and central Florida. Cuba is the specimen type locality.
The wing margins are scalloped. The upperside of the forewing is brown with dark brown and tan markings. The forewing has a V-shaped white spot near the center of the costa.

FLIGHT TIMES:

There are several flights throughout the year in the tropics.

ECLOSION:

Moths emerge from pupae in thin-walled cocoons under leaf litter.

SCENTING AND MATING:

Females call in the males with a pheromone released from a gland at the tip of the abdomen. Adults nectar at flowers, including petunia and Asystasia gangetica at dusk.

EGGS, LARVAE, PUPAE:

Females probably lay eggs on evening primrose (Onagraceae). In Florida larvae have been found on Black Mangrove (Avicennia germinans).
Larvae pupate in cocoons spun amongst leaf litter.
