DISTRIBUTION:
Isognathus
scyron
(Wing span: 72-73mm, females slightly larger than males),
flies in Surinam, the specimen type locality, and in
French Guiana, Cuba, Costa Rica.
FLIGHT TIMES:
There are probably several flights
throughout the year. Moths are on the wing continuously in Costa Rica.
ECLOSION:
Moths emerge from pupae in thin-walled cocoons
under leaf litter within 8-24 days of pupation.
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.

EGGS, LARVAE, PUPAE:
Females probably lay eggs on leaves of Apocynacea.
Larvae have
long tails; colouration suggests they are unpalatable to birds.
The pupae are also quite colourful, and, I suspect,
are very lively. Moths generaly emerge witin 8-24 days of
pupation.
