Renia factiosalis
Walker, 1859
Sociable Renia Moth, Dark-banded Renia
Renia factiosalis is a litter moth in the Erebidae, commonly known as the Sociable Renia or Dark-banded Renia. The was described by Francis Walker in 1859. It is widespread in eastern North America, ranging from southern Canada to Florida and Texas. The moth has a wingspan of approximately 24 mm and exhibits regional variation in number, with one generation in the northeast and multiple generations in southern .

Identification
Distinguished from other Renia by the dark banding pattern on the forewings. The specific epithet 'factiosalis' and 'Dark-banded Renia' reference this characteristic pattern. Separation from requires examination of wing pattern details; precise distinguishing features from similar species such as Renia discoloralis or other Herminiinae litter moths are not documented in available sources.

Taxonomic history
Described by Francis Walker in 1859. Placed in Herminiinae of Erebidae. The epithet 'factiosalis' appears to reference the banded ('fascia') wing pattern.
Regional generation variation
The documented north-south gradient in voltinism (one to multiple ) reflects phenotypic plasticity or local to thermal regime and growing season length.
