DISTRIBUTION:

Dirphia rengei (wingspan: males: 65-74mm; females: mm // Mfwl: 35-37mm; Ffwl: mm) flies in
Ecuador: Napo; Zamora-Chinchipe; at elevations of approximately 950-1770m.

"Dirphia rengei has a unique doubled postmedian line of the forewing in combination with a large triangular forewing dot, white pronounced veins, and the overall dark greyish brown colour."

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Specimens have been taken in February and April. There are probably additional flight months.

Larvae feed upon West Indian Locust (Hymenaea courbaril) and West Indian Cedar (Cedrela odorata).

ECLOSION, SCENTING AND MATING:

Males use highly developed antennae to locate females at night by tracking their airbourne pheromone plumes.

EGGS, LARVAE, COCOONS AND PUPAE:

White eggs with a black micropyle are laid in large clusters and larvae feed gregariously.

Typical of the Subfamily Hemileucinae, Dirphia species all have urticating spines.

The species name is indicative of .

It is hoped that this alphabetical listing followed by the common name of the anticipated foodplant will prove useful. The list is not exhaustive. Experimenting with closely related foodplants is worthwhile.
