DISTRIBUTION:

Pseudodirphia alba (wingspan: males: 68mm; females: larger) flies in Ecuador: Pastaza; and in Brazil: Amazonas.

The white fw basal and median areas distinguish this species. The hindwing is also entirely white.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

This species seems quite rare and may be diurnal.

Natural larval hosts are unknown, but Robinia is a likely choice and has been used with success by Kirby Wolfe for other species in this genus.

ECLOSION, SCENTING AND MATING:

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

At rest, moths fold wings over the body in typical Hemileucinae style.

EGGS, LARVAE, COCOONS, AND PUPAE:

Eggs are deposited in clusters or rings. Larvae are gregarious and are well equipped with urticating spines. A light, single-walled cocoon is spun among leaf litter.


It is hoped that this alphabetical listing followed by the common name of the anticipated 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.

Pseudodirphia was chosen as the genus name as these moths are very similar to those in the Dirphia genus.

The species name, alba, refers to all white hindwings and the white basal and median areas of the forewings.
