Synonyms and other taxonomic changes
Author of species is Boisduval, 1836 as Macroglossa diffinis. (Jean de Boisduval, French, 1801-1879, see also Wikipedia.)
Explanation of Names
Species name diffinis may be an eponym, as Diffin is a surname. There is a wasp Mesopolobus diffinis Walker, 1834--perhaps Diffin was an important entomologist or patron of research at that time. (Based on Internet searches.)

Adult: forewing clear area lacks partial crossband of dark scales near base; legs black; underside mostly black.

Larva: body usually green with black spots encircling spiracles, "leading edge of thorax yellow, with prominent granules, extended over back of head. Horn long, yellow at base, black from middle to apex."(1) A brown form also occurs.

Edges, fields with flowers. Adults feed actively on flower nectar during the day while hovering at blossoms.

Adults fly from March to September (two broods) in the south; shorter season in the north.
Food
Larvae feed on dogbane (Apocynum), honeysuckle (Lonicera), bush honeysuckle (Diervilla), and snowberry (Symphoricarpos). In Piedmont, North Carolina, seem to prefer the native Coral Honeysuckle (Lonicera sempervirens).
