ECLOSION, SCENTING AND MATING:

EGGS, LARVAE AND PUPAE:

Color morphs of larva courtesy of Dan Janzen.:

Adhemarius gannascus gannascus yellow morph.

Adhemarius gannascus gannascus green from (common).

Adhemarius gannascus gannascus pale green from with red dots.

Development from pupation to adult emergence is less than three weeks (sixteen to eighteen days). The pupa is dark chestnut, smooth and shiny. I suspect the larvae will pupate in dark buckets under layers of paper towels as opposed to more natural underground pupation.

Larval Food Plants

Listed below are primary food plant(s) and alternate food plants. It is hoped that this alphabetical listing followed by the common name of the foodplant will prove useful. The list is not exhaustive. Experimenting with closely related foodplants is worthwhile.
