Americerura scitiscripta, commonly known as the black-etched prominent , is a of prominent moth in the Notodontidae. It was originally described in the Cerura and Tecmessa before being placed in Americerura, a genus now restricted to the New World. The species is broadly distributed across North America, with active from early spring through autumn depending on latitude.

Identification

Distinguished from similar prominent moths by the fine, dark, etched line pattern on the forewings. The Americerura is separated from the Old World genus Cerura based on geographic distribution and morphological characters; A. scitiscripta is the only in this genus in most of its North American range.
