DISTRIBUTION:

Winbrechlinia winbrechlini (wingspan: males: 58mm; females larger than males; forewing length: males: 28-31mm; females: ??) flies in
Colombia: Magdalena: Sierra Nevada de Santa Marta: Municipio de Minco: Cerro Kennedy: San Lorenzo; 2525-2700m.

In his original description of this species, Brechlin also designated an AT female which has since (2018) been designated as the HT female of Winbrechlinia parbrechlini (Magdalena Department). Among other paratypes in the 2016 description of winbrechini are the male HT of W. sinjaevi (2018; Cesar Department) and the male HT of W. grissinjaevi (2018; Cesar Department).

The male is a uniform rusty brown, with a small diffuse black cell spot which is inwardly bordered by a paler, brighter, diffuse orange spot.

There is a slightly darker pm line that curves inward just above the cell, and there is a lighter suffusion on its outer edge, most visible along the curve to the costa. The hindwing cell and pm line are weakly defined. The post median area of all wings is a slightly darker, duller brown, lacking the more reddish tones of the basal and median areas.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Winbrchlinia winbrechlini flight months suggest it is double or even triple brooded or has a very irregular emergence pattern. Adults are on the wing In July, September and November. Only the male is known and it is sympatric with W. parbrechlini which so far is ony represented by the female holotype.

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.
