Definition
Nemoria darwiniata is a species of moth in the family Geometridae, commonly referred to as an emerald moth.
Overview
The species was first described by the entomologists Augustus Radcliffe Grote and Coleman T. Robinson in 1868. It occurs in North America, with records primarily from the eastern United States and parts of southeastern Canada. Like other members of the genus Nemoria, it is nocturnal and attracted to light sources. Adult moths are observed from late spring through early autumn, depending on local climate conditions.
Etymology / Origin
The specific epithet darwiniata appears to honor Charles Darwin, reflecting a tradition of naming new species after prominent naturalists. The genus name Nemoria derives from Greek, meaning “of the woods” or “forest‑dwelling,” consistent with the habitats of many Geometrid moths.
