DISTRIBUTION:

Procitheronia vanschaycki (wingspan: males: 92-108mm; females: 120-128mm // forewing length: males: 47-52mm; females: probably larger) flies in
French Guiana: Cayenne, Saint-Jean-du-Maroni, Saint-Laurent-du-Maroni, Kaw; and possibly westward to
Venezuela; and possibly eastward in
Brazil: Para and Mato Grosso; and the entire Guyano-Amazonian region.

It has been confirmed from Guyana: Potaro; Georgetown.

This species is very similar to the eastern Andean species, Procitheronia fenestratra, and the images on this page have been moved from the fenestrata file.

Procitheronia vanschaycki has a slightly more pointed forewing apex, and a lighter, more reddish appearance than P. fenestrata. I also note from the images in the Entomo Satsphingia journal that the white in the hindwing cell area is considerably reduced in P. vanschaycki compared to some images of P. fenestrata, but this character does not seem consistent across the range for P. fenestrata specimens. For instance, the very dark male fenestrata from Ecuador, provided by Horst Kach, also has reduced white on the hindwing. Perhaps the Ecuadorian population is of another species not yet described.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

There are possibly two generations annually with Procitheronia vanschaycki moths on the wing possibly in January, June and November-December. There may be additional flight months.

Procitheronia vanschaycki larvae will likely feed on Slow (Prunus spinosa) and Plum in captivity.

ECLOSION, SCENTING AND MATING:

Females extend a scent gland from the posterior tip of the abdomen after dark.

The slightly smaller, more brightly coloured males use their more highly developed antennae to locate the calling females, usually between midnight and 3:00 am.

Males of this subfamily have antennae which are quadripectinate for the basal two-thirds of their length.

EGGS, LARVAE AND PUPAE:

Eggs are large and yellow. Just before emergence, the tiny caterpillar becomes visible through the transparent eggshell.

Pupation is underground in a small cell.

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.

Prunus domestica....... Prunus spinosa

Plum Slow

Return to Procitheronia Index Return to Main Index 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. The source of the genus name Procitheronia is the likeness of members of this genus to the genus Citheronia. "Citheronia" is probably derived from Mount Citheron (Greek mythology), an untamed wilderness, exempt from the laws of civilization. The goddesses go naked there and are free from any of the pressures of society. The species name "vanschaycki" is honourific for Eric van Schayck.
