Schinia varix

Knudson, Bordelon & Pogue, 2003

Schinia varix is a small described in 2003, notable for its striking in coloration. Males display bright forewings with dark purple , while females have darker forewings with similar patterning. The is restricted to a narrow range in the south-central United States. Despite being collected as early as 1944, its formal description was delayed for nearly six decades.

Identification

Distinguished from other Schinia by the combination of with dark purple in males, black with yellow fringes, and small size. The darker female forewings separate it from similar yellow Schinia species. No other Schinia in its range combines this exact pattern of purple banding on yellow ground color.

Appearance

Small with length of 8.6–10.2 mm. Male forewings with dark purple in and subterminal areas; black with yellow fringes. Female similar but with generally darker forewings.

Habitat

Pine forests, oak-hickory woodlands, and areas with Gaillardia . Associated with sandy or gypsum-derived soils in the south-central United States.

Distribution

to south-central United States: eastern Texas, central Oklahoma, and Louisiana.

Seasonality

period from August to early October.

Host Associations

Gaillardia - probable larval Inferred from and distribution; have never been found
Pinus - feeding site observed feeding on various pines in 1944 collections
Ilex glabra - feeding site observed feeding on gallberry in Louisiana
Quercus - feeding site observed feeding on oak in Oklahoma
Carya - feeding site observed feeding on hickory in Oklahoma

Behavior

at night and have been observed feeding on various . Adults rest on flowers during the day, where their coloration may provide .

Ecological Role

Probable of Gaillardia and other flowering plants in its . feeding on diverse suggests opportunistic nectar feeding.

Human Relevance

Of interest to due to its restricted range, colorful appearance, and relatively recent description. The 1944 series was collected by lepidopterists but remained undescribed until 2003.

Similar Taxa

Other Schinia speciesMany Schinia share flower-visiting and colorful patterning, but S. varix is distinguished by its specific combination of /purple , black with yellow fringes, and small size restricted to the south-central US range.

Taxonomic history

First collected in 1944 in eastern Texas but not formally described until 2003 by Knudson, Bordelon & Pogue. The long delay between collection and description is unusual for such a distinctive .

Larval biology

Completely unknown. No have ever been found, and the larval remains speculative despite strong inference for Gaillardia based on and distribution.

Etymology

The specific epithet 'varix' refers to a dilated , likely alluding to a character visible in the .
