DISTRIBUTION:

Arsenura giuglarisi (wingspan: males: 132-138mm; females: 137mm) flies in
French Guiana: Roura: Piste de Belizon, Piste Coralie pk6,5 ? piste Changement pk7.5.

The basal area is enlarged by the position of the convex, diffuse, dark brown antemedian line, thereby shrinking the median area. The forewing cell mark is a thin wisp of a diffuse, slightly darker brown line. There are diffuse white patches near the anal angle of each wing. The presence of the strong, irregular, black band, following the outer edge of the brown postmedian band is diagnostic for the male.

The female is quite distinct.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

There is probably only one generation of Arsenura giuglarisi on the wing each year in January.

ECLOSION, SCENTING AND MATING:

Males use antennae to seek out females which scent at night.

EGGS, LARVAE AND PUPAE:

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.

I do not know the source of the genus name "Arsenura" chosen by Duncan in 1841.

The species name "giuglarisi" is honourific for collector Jean-Louis Giuglaris.
