DISTRIBUTION:

Adhemarius sexoculata (forewing length: 55 - 61mm, probably larger) flies in
Brazil;
Venezuela: Lara, Merida, Tachira;
Ecuador: Pichincha (October); Loja (November)
Bolivia: La Paz (August), Cochabamba (40m); and
Peru: Pasco.

Like the very similar Adhemarius tigrina, Adhemarius sexoculata lacks a dark area on the basal costa.
The two species can be differentiated by the presence of larger hindwing eye spots on veins CuA2 and 1A with an additional smaller spot on vein CuA1. Adhemarius tigrina lacks these eye spots.
The hindwing basal area of A. sexoculata is pinkish, while the same area in tigrina is yellow.

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.

José Oiticica Filho (1906 - 1964), the French entomologist/photographer who assigned the genus name, Adhemarius, possibly chose the name from Adhemarus, the fifth and last of the old counts of Querci (Verdun, France) who died in 880 AD.

The species name, sexoculata, recognizes the six swollen "eyelike" areas on dark veins of the hindwings.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Adhemarius sexoculata produces at least two broods annually with peak flights in February and July-August. It probably broods continuously, weather/climate permitting.

I recently received an image from Merida (elevation 2500m), Venezuela, from mid January.

Rick Buss writes of a sighting in Peru: "The actual sighting was October 15, 2006, in the Urubamba Cordillera at 3000 meters elevation. The specimen was in an open building where it had flown to fluorescent lights sometime during the night."

I have images from Ecuador in October-November.

Females are active from midnight until 1:30am with males on the wing from 12:30-2:30am.

Adhemarius sexoculata larvae probably feed upon Ocotea veraguensis, Ocotea atirrensis and Ocotea dendrodaphne.
