DISTRIBUTION:

Ormiscodes nigrosignata (wingspan: males: 50-63mm; females: 62-65mm) flies in
Chile: Arauco: Angol; Malleco: Termas de Manzanar; Valdivia: Valdivia; and Osorno: Pucatrihue and in
Argentina: Nequen.

It has been taken at elevations from 650-1500m.

The abdomen is orange, dorsally ringed in black. The ground colour is grey to brownish-black, darker in basal area and around white cell mark. The lines are thin, black and distinct with the aml angulate and the pml strongly and evenly scalloped, strongly recurved toward the body near the costa, and inwardly lined with white.

Specimens have been taken at elevations from 650m to 1500m.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Ormiscodes nigrosignata is probably double brooded throughout most, if not all, of its range. Adults are likely on the wing from February-March and November.

ECLOSION, SCENTING AND MATING:

Females extend a scent gland from the tip of the abdomen, and the males pickup and track the airbourne pheromone plume with their well-developed antennae.

EGGS, LARVAE, COCOONS AND PUPAE:

Early instar larvae typically feed gregariously. Late instar larvae become more widely dispersed on host trees and understory vegetation.

Larval Food Plants

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