DISTRIBUTION:

Neorcarnegia bispinosa (wingspan: males: 57mm; females: 87mm) flies in
central Brazil: Bahia (WO); Federal District (SN), Goias (SN); Mato Grosso (WO); and
eastern Bolivia: Santa Cruz and Chuquisaca, and
possibly northwestern Argentina: Jujuy (NV) at elevations from 750 to 1400m.

I am not sure of range differences between basirei and bispinosa, but I think bispinosa is from drier habitat in Brazil, western Paraguay, Bolivia and northwestern Argentina, while basirei is more likely limited to southeastern Brazil, southeastern Paraguay and possibly northeastern Argentina.

N. bispinosa has "a slightly more greyish ground colour, less falcate forewings in male and female and less elongated tips of the hindwing inner angle in males, larger size of the transparent parts of fore- and hindwings, and mainly in details of male genitalia (two sclerites on the vessica instead of one in N. basirei)" Naumann, 2006".

This species is also slightly smaller than N. basirei, and the pm line goes directly to the tip of the apex. On the ventral surface the am line is not developed

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Specimens have been taken in September, October, November, Neorcarnegia bispinosa possibly feed on Caesalpinia ferrea, Cassia and Machaerium acutifolium.

ECLOSION, SCENTING AND MATING:

Female Neorcarnegia bispinosa moths extend a scent gland from the posterior tip of the abdomen to call in the males.

EGGS, LARVAE AND PUPAE:

Females deposit slightly oblong, slightly flattened, translucent green eggs on hostplant foliage.

Larve form an incomplete tent-like cocoon, affixed to a hard substrate.

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.

Caesalpinia ferrea Cassia Machaerium acutifolium......

Leopard Tree Cassia Bastiao-de-arruda

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.

Stefan Naumann indicates the genus name "Neorcarnegia" was chosen by Draudt "reminiscent to the African genus carnegia Holland, 1896 which has some similarities in wing form and pattern (Bouvier 1931: 108)."

The species name "bispinosa" refers to the two sclerites on the vessica instead of one in N. basirei.
