Antaeotricha albulella
(Walker, 1864)
vestal moth
Antaeotricha albulella, commonly known as the vestal , is a small moth in the Depressariidae. First described by Francis Walker in 1864, it is distributed across the southeastern and mid-Atlantic United States. The species is characterized by predominantly white forewings with distinctive dark markings. It has been historically confused with the closely related Antaeotricha floridella, which occurs in drier sandhill of peninsular Florida.

Identification
Distinguished from Antaeotricha floridella by presence of black spots on forewings (A. floridella has white forewings). A. floridella also has pale gray hindwings versus white or pale gray in A. albulella. Genitalia dissection may be required for definitive identification. Forewing spotting pattern distinguishes it from other pale Antaeotricha in eastern North America.

Taxonomic history
Originally described as Cryptolechia albulella by Walker in 1864, later transferred to Antaeotricha. The concept was clarified through comparison with the newly described A. floridella in 2015, which helped define diagnostic characters for A. albulella.
Specimen verification
Reliable identification may require examination of genitalia, particularly for specimens from peninsular Florida where sympatry with A. floridella is possible.
