Any moth of the family
Sphingidæ, of which there are numerous genera and species. They are large, handsome moths with long narrow forewings capable of powerful flight and hovering over flowers to feed. They fly mostly at twilight and hover about flowers like a humming bird, sucking the honey by means of a long, slender proboscis. The larvæ are large, hairless caterpillars ornamented with green and other bright colors, and often with a caudal spine. See
Sphinx, also
Tobacco worm, and
Tomato worm. [

" The larvæ of several species of hawk moths feed on grapevines. The elm-tree hawk moth is Ceratomia Amyntor."
