Polyphemus Moth - (Antheraea polyphemus)

Authored By Staff Writer | Last Updated: 6/19/2015

The huge, seemingly drab, Polyphemus Moth shows flashes of color when it opens its wings.

This member of the Giant Silk Moth family is both large and furry. The antennae are also feathery. Eyespots on the wing are oval-shaped and have rings of yellow, black and blue in them. If startled, they will open and close their wings, flashing their eyespots as a way to disorient a would-be predator.

They can be found in parks and deciduous forests in urban, suburban and rural areas. Like most moths, they are nocturnal and attracted to lights.

Caterpillars are multicolored. Their soft bodies are covered in thin black, yellow and white rings. As it matures, it turns all white, retaining tiny black dots while growing 4 bristly spikes near its head. They eat a variety of plants and pupate on whatever they are eating.
