Doryodes tenuistriga

The combination of pale olive ocherous forewings with pale purplish marginal shading and whitish hindwings distinguishes this species. The pronounced sexual size dimorphism (female wingspan ~41 mm vs. male ~33 mm) provides additional diagnostic characters. Coastal Texas and Louisiana distribution restricts potential confusion to sympatric congeners.

Forewings pale olive ocherous with broad pale purplish shading along the costa and both inner and outer margins. Hindwings whitish. Wingspan approximately 33 mm in males, 41 mm in females.

Coastal environments in the western Gulf of Mexico region.

Coastal Texas and Louisiana, United States.

Adults active October and November.
