DISTRIBUTION:

Arsenura fuscata (wingspan: males: mm; females: mm // forewing length: males: 68-72mm in northern Peru; 62mm in Bolivia; females: probably larger) flies in
Bolivia: North Yungas, 100 km NE La Paz, -16.2, -67.6, 2008-11-01; and
Peru: San Martin: Rioja, collected by R. Marx, 2009-04-02;
Peru: San Martin, -7.18333, -79.4167, 2007-01-01. Mirror;
Peur: Loreto: Indiana; February 20, 2011 (DH).

Entomo-Satsphingia publication also indicates flight in Amazonas, Peru. This species has been taken at elevations of 800-1800m

This species is quite similar to A. armida and several other species in that group, but the male forewing apices are not nearly as produced, leaving outer margin of A. fuscata without concave region (only to a slight degree) below the apex.

Ground colour is almost uniform grey-brown showing less contrast than either A. arianae from Central America (Mexico to Nicaragua) and A. armida. A fuscata specimens from northern Peru also seem, on average, to have a forewing length about ten percent greater than the smaller arianae and armida.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Arsenura fuscata is on the wing in November in Bolivia and in January-February and April in Peru. There are probably additional flight months.

Larvae feed on ?

ECLOSION, SCENTING AND MATING:

Males use their 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 fuscata is probably indicative of a fuscus colouration of this species.
