DISTRIBUTION:

The Dotted Prince, Eosia insignis (forewing length: 18-25mm) (wingspan: males ; females: 45-55mm), flies in drier areas of
Kenya: Garba Tula, Mandera and Mtito Andei; with specimen type from the district east of Lake Rudolph, and probably in Kibwezi Forest and Kiboko.

Thierry Bouyer confirms it also flies in eastern Tanzania: probably Tanga, Dar Es Salaam and Morogoro.

Minetti Robert reports Eosia insignis from W. Udzungwa National Parc, Iringa Region, at 560m in Tanzania, taken December 10, 2006. I think the specimen from W. Udzungwa, Tanzania, is more likely E. minettii, and the female from Ethiopia is more likely digennaroi. Perhaps E. insignis is limited to Kenya and northeastern Tanazania.) The Eosia insignis HT female is from Rendile, Kenya.

The All Leps Barcode of Life website indicates a presence in southern central Ethiopia: between Nazret and Goba; (more likely this is E. digennaroi).

The day-flying male is yellowish-white with a dark irregular bar running from the outer 2/3 of the costa to almost the midpoint of the outer margin. Veins above the bar are dark and there is some additional dark scaling just below the apex on the triangular forewings. The hindwing is yellowish-white with a dark, scalloped outer margin.

In the female, there are a few black dots on the forewings and some yellow ones on the hindwings, both of which are a brownish pink. The forewing apex is toothed and the outer margins of all wings are irrregular.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Minetti Robert reports them on the wing in December in Tanzania, but this has been determined to be E. minettii. The HT female of Eosia insignis was taken in March of 1906 in Rendile.

Larval host are unknown.

ECLOSION, SCENTING AND MATING:

Females emit an airbourne pheromone and males track the scent with their antennae by flying in a zigzag pattern into the wind.

Thierry Bouyer describes this species as a "pierid like, day flying moth."

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", honour a contempory friend/collector/etc.

The genus name "Eosia", I believe, is another name for earth or large body of land.

The species name, "insignis" means remarkable or outstanding.
