DISTRIBUTION:

Xylophanes resta moths (wingspan: mm) fly in
Venezuela (specimen type locality) and south to
Ecuador;
Peru: Pasco: Oxapampa: Charapa; Puno: Carabaya: Santo Domingo; and
Bolivia: Santa Cruz: Manuel María Caballero, San Juan del Potrero; La Paz: Murillo, Valle de Zongo; Sud Yungas Yanacachi; Murillo, Zongo-Pacollo; Cochabamba.

Specimens attributed to Argentina are more likely Xylophanes anubus, although Ezequiel Bustos reports them in Tucuman, Argentina.

CATE: "Intermediate in appearance between Xylophanes aristor and Xylophanes tersa. Forewing somewhat broader than Xylophanes tersa; length: 36-41 mm.

"Tegula with a weakly developed golden medial line. Upperside of thorax with a grey medial band, bordered laterally and divided medially by brown lines, which is continued along the abdomen but becoming faint after first two abdominal segments. Golden-yellow lateral stripes on abdominal segments 3 to 6 more distinct than in Xylophanes tersa, with a patch of pale hairs and black patch anterior to it.

"Outer spur of midtibia longer than inner. Abdominal sternites without distinct lines.

"Forewing upperside with a characteristic brown tone; first postmedian line very strong basally but disappearing towards the apex; second postmedian line fused basally with the first (as in Xylophanes eumedon); fourth postmedian line less than half the width of the first.

"Forewing (and hindwing) underside brighter than in Xylophanes tersa, the brown markings consequently more prominent; a straight brown line, in some places indistinct, crossing the wing parallel to distal margin, crossing M3 about 1.5–2 mm. from discal cell; marginal area not, or only slightly, darker than disc; a weakly defined yellow costal patch present apically (similar to that in Xylophanes titana).

"Hindwing upperside with pale yellow spots of median band larger than in Xylophanes tersa, the more distal closer to the margin; all separate apart from those from CuA2 to 2A; small marginal spot at anal angle.

"Marginal area of hindwing underside divided by the veins, which are pale orange."

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.

Jean Marie Cadiou writes, "When I say "Xylophanes" in English I pronounce it something like "Zailophanees", with the emphasis on the "o". The French pronounce it differently, something like "Kzeelophaness" with no emphasis, and the Germans yet in a different way..."

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.

"Xylophanes" sounds like it is from Greek mythology, and resta, in Greek, means the remainder or leftover.

FLIGHT TIMES:

Xylophanes resta adults probably brood continuously.

ECLOSION:

Pupae probably wiggle to surface from subterranean chambers just prior to eclosion.

SCENTING AND MATING:

Females call in the males with a pheromone released from a gland at the tip of the abdomen. Males come in to lights very readily, but females are seldom taken in that way.

EGGS, LARVAE, PUPAE:

Larvae probably feed on plants of the Rubiaceae and Malvaceae families.

Moths emerge approximately one-two months after larvae pupate.
