Amphion floridensis Clark, 1920
First described in 1777 by Pieter Cramer
as Sphinx nessus
. This name was invalid, because Dru Drury
had already used it for another species in 1773. Both Cramer's and Drury's "Sphinx nessus" were moved to different genera, but that makes no difference as far as the rules are concerned.
The only valid name available as a replacement is floridensis
, which B.P. Clark
had used in 1920 to describe a proposed subspecies.
Adults fly April-July in the north, 2 broods in the south (1)
Larvae feed on Ampelopsis, grape, and cayenne pepper. Adults nectar at flowers during the day and at dusk:
Egg, larvae, pupa, and adult:
Caterpillars pupate in shallow underground chambers.
Covell notes that this was formerly known as A. nessus
and calls it A. floridensis (1)
, but the more recent Arnett still reflects A. nessus (2)
