DISTRIBUTION:

Dirphia abhorca (wingspan: males: 65-75mm; females: 73-98mm // Mfwl: 35-40mm; Ffwl: 40-55mm) flies in
western Colombia: Valle del Cauca and Nariono; and
western Ecuador: Pichincha and Cotapaxi, along the Pacific Coast at moderate elevations (650-1700m).

In both the male and the female, the pm line is convex and relatively close to the outer margin. The very angulate am line does not extend up along the costa very much, not even as far up as the thick white upper branch of fork which shows a strong presence of a yellow striga. The inward pointing portion of the white fork is evenly divided longitudinally by a thin brown striga.

In some locales it flies sympatric with Dirphia subhorca.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Moths have been taken in February, April-May-June and August-September and November, suggesting at least three broods.

Larval hosts are unknown.

August 1970, 1700m, on my home computer only.

ECLOSION, SCENTING AND MATING:

Males use highly developed antennae to locate females at night by tracking her airbourne pheromone plume.

EGGS, LARVAE, COCOONS AND PUPAE:

Eggs are laid in large clusters and larvae feed gregariously. Typical of the Subfamily Hemileucinae, Dirphia species all have urticating spines.

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", honoura contempory friend/collector/etc.

I do not know the source of the genus name "Dirphia" chosen by Hubner in 1819.

The species name "horca", possibly comes from the Spanish word (horca) for fork and might refer to the reduced or absent extension of the thick, creamy white 'fork' toward the postmedial line.
