Eralea albalineella

The extremely small size (7 mm wingspan) and occurrence in the southern and eastern United States may help distinguish this species from other Cosmopterigidae, though definitive identification likely requires examination of genitalia or other microscopic features not described in general sources.

Small moth with a wingspan of approximately 7 mm. Specific coloration and pattern details are not documented in available sources.

Specific habitat preferences are not documented. Based on its geographic range, it occurs in diverse environments including temperate deciduous forests, coastal plains, and arid regions of the southwestern United States.

Recorded from West Virginia, South Carolina, Louisiana, Florida, Texas, and California. The distribution spans the southeastern and south-central United States westward to California, suggesting broad adaptability across varied climatic zones.

Adults have been recorded on wing from April to July, and again in September and November. This pattern indicates a spring-summer generation with possible autumn activity, though whether this represents one or multiple generations per year is unclear.

Larval stage and pupation details are unknown. The presence of adults across multiple months suggests at least one generation annually, possibly more.

• Other Eralea speciesCongeneric species share small size and general Cosmopterigidae morphology; reliable separation requires detailed examination.
• Other CosmopterigidaeMany members of this family are similarly minute with reduced wing patterns; geographic distribution and genitalia dissection are typically needed for identification.
