Explanation of Names
In Greek mythology, Achemon (also spelled Acmon) was one of two mischievous brothers called the Cercopes
Wingspan 87-96 mm.(1)
Larva probably similar to Pandorus sphinx, to about 90 mm (3.5")
Larvae may be tan or green, with white diagonal elongated/segmented spiracular spots from A3 to A7. "Horn" on tail end is lost after the fourth instar. Pupates in burrows in the soil.
"Maine west to North Dakota and southern Oregon; south to south Florida, southern California, and Mexico." (BMNA)
Larvae feed on leaves of grape (Vitis), Virginia Creeper (Parthenocissus), Ampelopsis and related vining plants.

Adults take nectar from flowers.
Life Cycle
egg and first instar larvae; older larvae; older larva; adult

Caterpillars are similar to Pandorus Sphinx, and eat a similar range of plants, but Achemon has narrow segmented spots on each segment from A3 - A7, instead of Pandorus's single large one.
