DISTRIBUTION:

Arsenura biundulata (wingspan: males: 129-158mm; females: 146-160mm // forewing length: males: 83.2mm; females: 88-88.6mm) flies in
southeastern Brazil: Rio Grande do Sul, Sao Paulo, Parana, Santa Catarina.

Arsenura biundulata

Arsenura aspasia

Note greater extension of white lobes toward outer margin on forewing postmedian line of Arsenura biundulata to the far left, compared to almost smooth bend in the same area on Arsenura aspasia to the immediate left.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

There are probably two generations of Arsenura biundulata annually with adults on the wing in January-February-March-April-May and then again in July, suggesting two or three annual broods.

EGGS, LARVAE AND PUPAE:

Listed below are primary food plant(s) and alternate food plants listed in Stephen E. Stone's Foodplants of World Saturniidae. 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 "biundulata" probably refers to the two major undulations near the outer margin of the wings.
