Eudryas

Eudryas is a genus of moths belonging to the family Noctuidae. They are part of the subfamily Agaristinae, also known as the Forester moths or Wood Nymph moths. The genus is native to North America.

Eudryas moths are generally medium-sized and possess distinctive patterns, often featuring combinations of white, brown, and black markings. The larvae, or caterpillars, of Eudryas species feed primarily on plants in the family Vitaceae, which includes grapevines. This association with grapevines makes them of interest in viticulture.

Common species within the Eudryas genus include Eudryas grata (Beautiful Wood-Nymph) and Eudryas unio (Pearly Wood-Nymph). These species are distinguished by subtle variations in their wing patterns and geographical distribution.

The adult moths are typically active during the daytime, a characteristic that separates them from many other Noctuidae moths, which are often nocturnal. This diurnal behavior, coupled with their distinctive patterns, makes them relatively easy to observe in their natural habitats.
