Argyria lacteella

Fabricius, 1794

milky urola moth, Southern Milky Argyria Moth

A small crambid with a wingspan of approximately 11 mm, distinguished by milky-white to pale gray coloration. Taxonomic identity was recently clarified through hybridization capture from the 1794 Fabricius lectotype, resolving decades of confusion with the widespread North American now assigned to Argyria gonogramma. The species occurs primarily in the southeastern United States, Caribbean, and Neotropics. are active from spring through fall.

Identification

Distinguished from the superficially similar Argyria gonogramma (formerly misidentified as A. lacteella) by morphological characters and COI barcode sequences; all in this complex share approximately 11 mm wingspan with previously unrecognized external diagnostic characters that require detailed morphological examination. The lectotype DNA barcode firmly establishes species identity against the 229 available Argyria sequences in public databases.

Distribution

Southeastern United States from Maryland south to Florida and west to Texas; Caribbean including Cuba, Puerto Rico, and Bermuda; extending through Central America ( Rica) to South America (Brazil). Distribution circumscribed from slightly more than 800 specimens. Not to be confused with the widespread North American now assigned to A. gonogramma.

Seasonality

on wing from spring to fall.

Human Relevance

Subject of significant taxonomic research using novel museomics techniques; the hybridization capture protocol developed for this demonstrates the potential to recover genetic information from 18th and 19th century , with applications for resolving taxonomic problems across .

Misconceptions

The name A. lacteella was incorrectly applied to a widespread North American for many years; the true A. lacteella has a more restricted southeastern US and Neotropical distribution. The name A. pusillalis Hübner, 1818 is a associated with A. gonogramma, not A. lacteella.
