Orthogonioptilum occidentalis inhabits Burkina Faso (RR), Africa. Philip Darge reports it only from
Liberia: Bong Town; and
the Ivory Coast: Lamto and Adzope.

All Leps Barcode of Life reports it in Guinea, Burkina Faso;
southern Cameroon and southwestern Central African Republic.

Rodolphe Rougerie and Jeremy Bouyer confirm it in Burkina Faso in 2005.

Thierry Bouyer indicates this moth resembles other species in the violascens group. In this group, the individual species' variability makes identification very difficult without examining the genitalia.

Male forewing length is from 31-36mm. The only means of identification is by examining the arm of the male genitalia... 8th tergite....

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

This moth flies in May-June and again in October as a bivoltine species.

Orthogonioptilum occidentalis larval hosts are unknown.

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.

Orthogonioptilum comes from the Greek words for right-angle and wing, according to Pinhey.

The species name, 'occidentalis', indicates the range in western Africa.
