Diet and Habitat Larvae of this moth eat the underside of the leaves of wild grapes, cultivated grapes, Virginia Creeper, and peppervines. Adult moths eat nectar from flowers of herbaceous (no wood stems above ground). Adults specifically eat from sweetleaf (Symplocos tinctoria).

This moth is native to Canada and can be found in eastern and central Northern America from Nova Scotia to Florida and South Dakota to Texas. It is also found in Mexico according to Moth Identification. They inhabit wooded areas that meet open fields as the fields have flowers to feed the adults and the wooded areas have grapevine and Virginia creeper to feed larvae.

Mating This species are univoltine (one brood a year) in the north, mating from April to June. In warmer climates there may be two to three broods a year, mating in April to June then in August. Eggs are lain on grapevines and Virginia creeper in the summer. Pupae overwinter in soil or wood cracks.

Predators This moth is preyed on in all stages of life and are dinural (active during the day). Larvae spit an orange tinted liquid when threatened and escape by attaching a line of silk threat to its perch from its mouth, then falling off the perch.

Fun Fact

The larvae of this species can be considered pests to commercial and decorative vineyards.

This moth has two subspecies: Alypia octomaculata octomaculata (Fabricuis, 1775) and Alypia octomaculata matuta (H. Edwards, 1883)

This species pupae can go into a dormant state while called a “diapause” where development is delayed. The longest recorded time for this species is 4 years. The reason this species exits a diapause is unknown.
