DISTRIBUTION:

Periga pachijalensis (wingspan: males: 63mm; females: // forewing length: males: 33-35mm; females: mm) flies in
Ecuador: Pichincha, at elevations of 900-1000m.

On average this species is slightly larger than Periga elsa which has a male forewing length of 30-32mm.

This species belongs to the Periga cluacina Subgroup, which consists of the following species:


Periga cluacina
Sorry, no image available at this time. Similar to P. costaricana. Barcoding might be required to differentiate between them; perhaps they will be synonymized, or costaricana will replace cluacina in CR. Elsa: once treated as cluacina subspecies.
Panama, Costa Rica?

Periga costaricana
Cosat Rica

Periga elsa
W Colombia; W Ecuador

Periga herbini
Eastern Ecuador

Lemaire indicates herbini and extensiva may require examination of genitalia to distinguish beteen them.

Herbini possibly flies at lower elevation (800-1300m) than does extensiva (1350m)

Periga extensiva
Eastern Ecuador

Periga armata
Colombia: Cundinamarca

Periga inexpectata
Co: Putamayo; Ec: Sucumbios
probably not inexpectata

Periga occidentalis
Colombia; Ecuador; Peru??

Periga kindli
French Guiana

Periga squamosa
Peru; Bolivia

Periga pachijalensis

Members of the Periga cluacina Subgroup generally have each forewing with two small but distinct white cell spots, completely outlined in black or very dark brown, with the spots connected at least partially by a thin, dark, convex arc with a small dark spot near its center. In the yellowish and grey brown species (kindli and squamosa), the forewing antemedian line is strongly indented at the cubitus. This last feature is not present in the orangey species: armata, inexpectata and occidentalis.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Moths are on the wing in January, April, June and December. There may be additional flight months. Larval hosts are unknown.

ECLOSION, SCENTING AND MATING:

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

EGGS, LARVAE, COCOONS AND PUPAE:

Eggs are probably deposited in clusters on hostplant foliage.

Periga galbimaculata larvae are highly gregarious and have the urticating spines typical of larvae from the Subfamily Hemileucinae.

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.

The pronunciation of scientific names is troublesome for many. The "suggestion" at the top of the page is merely a suggestion. It is based on commonly accepted English pronunciation of Greek names and/or some fairly well accepted "rules" for latinized scientific names.

The suggested pronunciations, on this page and on other pages, are primarily put forward to assist those who hear with internal ears as they read.

There are many collectors from different countries whose intonations and accents would be different.

Some of the early describers/namers chose genus and species names indicating some character of the insect, but more often, they simply chose names from Greek or Roman mythology or history.

Those species names which end in "ensis" indicate a specimen locale, and those which end in "i", pronounced "eye", honour a contempory friend/collector/etc.

I do not know the source of the genus name "Periga" chosen by Walker in 1855.

The species name "pachijalensis" is indicative of a specimen type locale in Rio Pachijal, Pichincha, Ecuador.
