Subfamily: Sphinginae, Latreille, [1802]
Tribe: Sphingini, Latreille, 1802

DISTRIBUTION:

Cocytius mortuorum (Wing span: approximately 111-130-140mm, males smaller than females), flies in
Brazil;
Panama: Darien NP, Darien: Rando Frio (GJ);
Colombia;
Ecuador;
Peru: Junin (HM);
and Bolivia: La Paz: Murillo, Río Zongo, 750m; and
French Guiana: SGO.

I suspect it also flies in Venezuela Amazonas (JRAC), Guyana and Suriname.

This moth will most often appear in reference work as Cocytius mortuorum until the new designation as the single species in the Morcocytius genus designation becomes more wiedely known.

FLIGHT TIMES:

Cocytius mortuorum adults nectar at flowers and probably brood continuously. Specimens are reported from October and November in Peru. There are reports from French Guiana for March and April.

ECLOSION:

Pupae probably wiggle to surface from subterranean chambers just prior to eclosion.

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 Guatteria diospyroides, Annona purpurea, Annona reticulata, Xylopia frutescens and Custard apple (Annona glabra) and probably other members of the Annonaceae family.

Moths emerge from pupae in as few as 21 days from pupation.
