DISTRIBUTION: Heniocha marnois, The Marbled Emperor (wingspan: males: 65-84mm; females: 80-92mm), flies in East and Central Africa from the eastern Cape province through Natal and Transvaal, South Africa and Zimbabwe into Zambia: Central Province Kasanka N. P., south-western and southeasternDemocratic Republic of the Congo (Zaire): Kasanga: Sakania; and Tanzania. It is also possibly present in Botswana. Rolf Oberprieler confirms it for Namibia, and Thierry Bouyer confirms it for Malawi. The moth is also "recognized" on a Central Africa Republic Stamp, but the species depicted is probably H. apollonia. RO

Rolf Oberprieler writes, "The CAR stamp does not depict H. marnois (has hindwing eyespots, which occur in the apollonia group, not the dyops group!). It is possible that H. marnois still occurs in CAR, but there's another similar species up there, H. vingerhoedti, which appear to replace H. marnois in the north-west."

Heniocha marnois larvae feed on Acacia mollissima (Black wattle), A. erubescens (Blue thorn), A. nigrescens (Knob thorn), A. mellifera (Black thorn), A. fleckii (Plate thorn), A. burkei (Black Monkey thorn) and A. polyacantha (White thorn), and, based on Sue Bentley's report, probably on Acacia sieberiana var. woodii (Paperbark Thorn).

Adults are on the wing in October-November and then again in February.

ECLOSION, SCENTING AND MATING:

Mating takes place at night and both sexes, the female being larger, come into lights.

EGGS, LARVAE, COCOONS AND PUPAE:

Eggs are deposited in small rows of 6-10 on foodplant leaves. Larvae are at first gregarious becoming more solitary after the second instar when they begin hiding on the undersides of leaves and branches. Silvery spines provide excellent camouflage against a light sky. Lengths of 65 mm are achieved before larvae descend trees to pupate in soil.

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.

In Greek mythology Heniocha is the daughter of Pittheus and the mother of Sciron.

Pinhey indicates the species name marnois means "struggling" in Greek.
