Family: Sphingidae, Latreille, 1802 |
I do not know exactly where the transition is between this subspecies and nominate Madoryx plutonius plutonius.

The larva feeds on Conostegia xalapensis and has eyes and a false face as does Madoryx oiclus, but the body is more moss colored and has fine green flecking.Larvae spin loose cocoons of yellow silk and leaves, but the cocoon is not nearly as tight as is the Madoryx oiclus cocoon or the Madoryx bubastus cocoon.

The pupa is dark chocolate brown with faint beige 1/2 moon false eyes on the real eyes. The abdominal segments 4,5,6 have posterior 2 mm dull yellow to give the 3 striking yellow rings. When the pupa is removed from its cocoon, the pupa snaps back and forth like a snake. It is an extremely active pupa. The cocoon is really just a bit of disorganized silk sticking leaves together. |
I do not know the origin of the genus name "Madoryx".
The species name, "pluto", is derived from the Pluto of Greek religion and mythology. Pluto is the god of the underworld, the son of
Kronos and Rhea. He is also called Hades. After the fall of the Titans, Pluto and his brothers Zeus and Poseidon
divided the universe, and Pluto was awarded everything underground.
The subspecies name, dentatus, is indicative of the dentate nature of the curve below the forewing apex. In the nominate subspecies
from South America, the curve is smooth (not dentate). Those who first published descriptions and assigned scientific names to many insects, simply chose names of
biblical or mythological origin without any real descriptive qualities. Their purpose was simply to set a standard for purposes
of identification by assigned name. On some occasions, names, mostly of Latin or Greek origin, were chosen to signify a particular
character of the genus or of an individual species.
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.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.
