DISTRIBUTION:

Periga prattorum (wingspan: males: 64-69mm; females: 73mm // forewing length: males: 35-36mm; females: 38mm) flies in the
South Andean region of Peru: Amazonas, Madre de Dios, Cusco, Puno,
Ecuador: Pastaza; and in
Bolivia: La Paz, in low elevation andean forests (310 m - 1200m).

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Moths are on the wing in May and November-December. There may be more than two broods annually.

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 prattorum 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 "prattorum" is honourific for A. E. and F. Pratt, who provided the holotype.
