DISTRIBUTION:

Winbrechlinia grissinjaevi (wingspan: males: mm; females larger than males; forewing length: males: mm; females: 36mm) flies in
Colombia: Cesar: Sierra Nevada da Santa Marta: near Pueblo Bella at elevations of 2700m.

This moth was originally treated as a paratype of Winbrechlinia winbrechlini. This species is similar to W. sinjaevi, but grissinjaevi is much greyer than the reddish-brown sinjaevi with which it is sympatric near Pueblo Bella.

Thus far known from only a single female, it seems smaller than both sinjaevi and parbrechlini. This species seems not as dark as shapiroi and lacks the expected larger dark cell spot. Instead, the outer edge of the forewing cell is just a slightly darker striga. The hindwing cell of grissinjaevi has a very small, diffuse back spot just inside the outer edge of the cell.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Winbrchlinia grissinjaevi is probably single brooded throughout most, if not all, of its range. Adults are on the wing in September. There are probably additional flight months, although the species might be single brooded.

ECLOSION, SCENTING AND MATING:

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

Adults rest during the day on the foliage or trunks of pines or other hosts, flying only at night. Both males and females respond to light.

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.
