Pheosia rimosa, the black-rimmed prominent moth, fissured prominent or false-sphinx, is a moth of the family Notodontidae. The species was first described by Alpheus Spring Packard in 1864.[1][2] It is found from coast to coast in North America, although it is less common in the south-eastern United States.[3]
The wingspan is 43–62 mm.[4] Adults are on wing from spring to fall.
The larvae feed on the leaves of Populus and Salix species.
Pheosia portlandia was previously treated as a distinct species, replacing P. rimosa in Pacific coastal forests. Research has concluded that Pheosia portlandia is a synonym of P. rimosa.
