Diathrausta reconditalis

The combination of small size (18 mm wingspan), dark brown to black wings with greenish iridescence, and three white forewing spots distinguishes this species from most North American crambids. Similar Diathrausta species may share the general color pattern but differ in spot number, arrangement, or wing shape. The greenish reflections are particularly noticeable in fresh specimens and under certain lighting conditions.

A small moth with wingspan approximately 18 mm. Forewings and hindwings dark brown to nearly black with greenish metallic reflections. Three distinct white spots present on each forewing, arranged in a characteristic pattern. Body slender, typical of crambid moths.

Specific habitat associations are not well documented. Based on distribution records, occurs in varied environments across eastern deciduous forests, mixed woodlands, and adjacent open habitats. Adult records span multiple ecological zones from coastal plains to Appalachian regions.

Eastern and central North America. Documented from: Alabama, Arizona, Florida, Indiana, Kentucky, Maryland, Massachusetts, Mississippi, New Hampshire, New York, North Carolina, Ohio, Oklahoma, Ontario (Canada), South Carolina, Tennessee, Vermont, and West Virginia.

Adult activity period not precisely defined in available sources. Observations span multiple months but specific flight season requires further documentation.
