Synonyms and other taxonomic changes
Author of species is Fabricius, 1775, as Sesia thysbe. At one time the species was described under Haemorrhagia Grote (1).
Explanation of Names
Pyramus (πυραμο&sigmaf); and Thisbe (θισβη) were lovers who died tragically--Pyramus found Thisbe's blood-stained scarf, assumed she had been killed, and committed suicide with his sword. It seems likely the reference to the story of Thisbe is a reference to the rusty, somewhat blood-like coloration of this moth. Certainly the application of the genus Haemorrhagia is a reference to blood-like coloration. In support of this idea, Fabricius described a butterfly as Papilio pyramus in 1781, though this is no longer a valid name. This species, in the Nymphalidae, is now apparently Haematera pyrame. An image found on the Internet shows that it has a prominent reddish-orange patch on the upperside of both wings.
Size
Wingspan 40-55 mm
Identification
Adult: forewing clear area has partial crossband of dark scales near base, and distal margin of clear area is uneven or ragged-edged (not smooth-edged); legs pale/whitish (vs. reddish in gracilis and black in diffinis). Underside mostly white in front, extending to front legs, then reddish behind, unlike mostly black underside of H. diffinis.
Range
Alaska through central and eastern North America
Habitat
Open areas with shrubs, young trees, gardens. Adults feed actively on flower nectar during the day while hovering at blossoms.
Season
Adults fly from April to August (one flight) northward; March-June and August-October (two flights) in the south.
Food
Larvae feed on hawthorn, honeysuckle, snowberry, viburnum.
Adults take nectar from deep-throated flowers.
Life Cycle
Two generations per year in the south; one in the north.
Remarks
Beautiful, but moves so quickly it can be hard to appreciate.
