(Smith, 1797)
placentia tiger moth
Apantesis placentia, commonly known as the placentia , is a of tiger moth in the Erebidae. First described by James Edward Smith in 1797, this species occurs in the southeastern United States. It was formerly classified in the Grammia but was transferred to Apantesis along with related genera. The species produces at least two annually and is associated with sandy, open woodland .

Identification
This can be distinguished from similar by its geographic restriction to the southeastern United States coastal plain. Formerly placed in Grammia, species in that complex were reclassified to Apantesis based on morphological and molecular data. Precise identification from requires examination of genitalic characters and pattern details not fully specified in general sources.

Taxonomic history
This was originally described as Phalaena placentia by James Edward Smith in 1797. It was subsequently placed in Grammia, then transferred to Apantesis as part of a major generic reclassification of that incorporated species from Grammia, Holarctia, and Notarctia into an expanded Apantesis based on molecular and morphological evidence.
