Grote, 1864

Little Dark Gem

Schinia villosa, commonly known as the Little Dark Gem, is a small first described by Augustus Radcliffe Grote in 1864. It is primarily a western North associated with montane , though its range extends eastward across the Canadian prairies. The species exhibits the typical Schinia trait of flower-visiting , with active in mid-summer and feeding on Asteraceae .

Identification

Distinguished from other Schinia by its small size (wingspan ~20 mm), dark coloration implied by , and geographic distribution centered on western montane regions extending to the coast ranges. active July-August. Larval plants (Aster, Erigeron, Eucephalus ledophyllus) may aid identification where these plants occur. Similar small in the same should be examined for pattern and characteristics.

Appearance

Small with wingspan approximately 20 mm. Like other members of Schinia, are typically colorful and flower-associated. Specific coloration patterns are not detailed in available sources, but the 'Little Dark Gem' suggests relatively dark, possibly iridescent or metallic coloration compared to other Schinia .

Habitat

Western montane including mountain ranges and adjacent plains. Found in environments supporting larval plants in Asteraceae, including open meadows, grasslands, and montane forest edges where Aster, Erigeron, and Eucephalus occur.

Distribution

North America: primarily western mountain from coast ranges of Washington and British Columbia south to Arizona. Range extends eastward across plains through Alberta and Saskatchewan to southern Manitoba.

Seasonality

on July to August, with exact timing varying by location and elevation.

Diet
