Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Forbes (1948); Hodges (1971); Tuttle (2007)Technical Description, Immature Stages: Forbes (1948); Wagner (2005); Tuttle (2007)                                                                                 
Adult Markings: A small day-flying Sphinx. Like Hemaris species, Amphion is a bumblebee/hummingbird mimic, possessing two distinctive yellow rings on its abdomen and a tuft of feather-like scales at the tip of the abdomen; unlike Hemaris, however, the wings are opaque rather than transparent, brown on the forewings and reddish on the hindwings. Sexes are similar.
Wingspan: 3.7 - 5.5 cm (Covell, 1984)
Adult Structural Features: The tongue is well-developed.
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Larvae are green in early instars but brown in the last ones; they rest on the ground during the day (Forbes, 1948; Wagner, 2005). The head is relatively small and squarish (Forbes, 1948). In addition to the obscure oblique lines along the sides, a pale subdorsal stripe is also present. Pupation occurs underground.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: Potentially occurs statewide, though more data are needed on its exact habitats.

Habitats and Life History
Habitats: Many of our records come from barrier islands where grape tangles occur in dune habitats. Elsewhere, our records come primarily from wet to mesic hardwood-dominated forests. The widespread distribution of its host plants suggests that it could be found in a range of habitats.
Larval Host Plants: Larvae are stenophagous, feeding on members of the Vitaceae. Wagner (2005) lists grape (Vitis), Virginia Creeper (Parthenocissus quinquefolia), and peppervine (Ampelopsis). In North Carolina, we have observed larvae feeding on grape and Virginia Creeper. - View
Observation Methods: Look for this species in the daytime or at dusk visiting flowers. Also visits fruit, feces, sap and wet sand. It responds well to fermented baits and traps often demonstrate that the species can be quite common in area where it has otherwise never been seen. None of our records come from lights.

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: G5 SNR [S4S5]
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: This species is far less commonly observed than Hemaris thysbe or H. diffinis, two other day-flying species that visit flowers. Use of baits during its daytime flight period may provide a more accurate picture of its distribution and abundance within the state. The frequency of citizen scientist records suggests that the species may relatively common, but undersampled due to its diurnal habits.
