Synonyms and other taxonomic changes
First described in 1779 by Pieter Cramer
as Sphinx myron
Explanation of Names
from Greek myron (μυρον)- literally "sweet oil or perfume", figuratively "something graceful or charming"
very common; sometimes abundant
Adult: forewing has muted "army camouflage" pattern - variably dark brown to pale yellowish-gray, often with green shading (some adults are completely shaded in various tones of green); PM line slightly curved; dark discal dot and pale shading in median area; dark AM and PM bands, and dark patches at apex and anal angle; hindwing brownish-orange
Larva: freshly-emerged larvae have a slender yellowish body, relatively large brown head, and disproportionately long black anal horn; mature larvae have a green or brown body with a white stripe along the side smudging downwards into diagonal stripes. Head and anterior thoracic segments slender in mature larvae (body swells greatly at third throacic segment, as in Azalea Sphinx). Spiracular spots small and orange, edged top and bottom with white dots. Horn granular.
Eastern and central North America: Nova Scotia to Florida, west to Texas and New Mexico, north to Manitoba
Woodlands and edges near hostplants; adults are nocturnal and attracted to light
adults fly all year in Florida; March to September elsewhere
larvae present from April to November
Larvae feed on leaves of peppervine
, grape, and Virginia Creeper (Parthenocissus quinquefolia
Adults take nectar.
one or two generations per year in the north; two or more generations in the south
Caterpillar development by Tom Murray:
is larger, less common, has a complex pattern of lines and patches along inner margin of forewing, and lacks orange on hindwing
of both species at CBIF)
) forewing has a straight PM line and lacks green shading (compare images
of both species at CBIF)
Larvae of Azalea Sphinx
are similar, but their hostplants will usually help to distinguish them (however, both species share Viburnum
spp. as foodplants).
