Other Common Names

Trumpet Vine Sphinx

Numbers

the only species in this genus in North America (and the world) listed at All-Leps
uncommon

Size

Wingspan 60-75 mm

Identification

Adult: forewing pale gray to grayish-brown with distinct white reniform spot; black basal dash projects like a thorn from inner margin (an important feature); 3 or 4 black longitudinal dashes near middle of wing intersect 2 dark lines, often diffuse or indistinct, completely crossing wing in postmedial area; hindwing mostly dark gray with white and dark checkered fringe

Range

Eastern United States plus southern Ontario; also occurs in Mexico.

Habitat

Fields, edges, with hostplants, and nearby areas; adults are nocturnal and come to light.

Season

Adults fly from April to October in the south [Charles Covell]. Bill Oehlke reports flight seasons of May-July in the north, and March-November (2 broods) in the south. In Durham, North Carolina, Patrick Coin recorded this species at the same lighted wall on these dates: 5/28, 6/9, 6/22, 7/12, 8/13, 8/22.

Food

Larvae feed on Trumpet Creeper (Campsis radicans), Yellow Trumpetbush (Tecoma stans), passionflower (Passiflora spp.), and lilac (Syringa spp.)
Adults take nectar from deep-throated flowers.

Life Cycle

Caterpillars hide on underside of foliage during day, and emerge to feed at night. First brood pupates in soil, emerges later that year (if two broods). Overwinters as a pupa in chamber in soil.

See Also

easily distinguished from Waved Sphinx (Ceratomia undulosa) by black basal dash on forewing - lacking in undulosa (Waved Sphinx also has several wavy lines completely crossing forewing, whereas Plebeian Sphinx has only two lines - compare images of both species at CBIF)
distinguished from Northern Apple Sphinx (Sphinx poecila) and Apple Sphinx (Sphinx gordius) by lack of subterminal line projecting from inner margin of forewing (compare images of all 3 species at CBIF)
