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.
I do not know the source of the genus
name "Eacles", but it may be a combination of
"Ea", the Greek word for gods and goddesses and the Greek
suffix "cles", meaning 'glory of'.
The species name "imperialis" is probably for the majestic
appearance and colouration of this moth.
The subspecies name "opaca" means opaque or dull.
This moth does not have the bright yellow ground colour
of other imperialis subspecies.
