Epirrhoe alternata (Muller, 1764)
Description: Wingspan 27-30mm. Adults are richly marked and often quite variable. The wing colour is generally white, although most of this is obscured by the greyish markings on the outer margin of the forewings and darker central band, which in some individuals may be broken or incomplete. The area between is generally white with a pale grey line.
Key Identification Features:
Flight Period: From the beginning of May to early September.
Status: Common and widespread throughout all counties including Rathlin Island, Antrim.

They are frequently encountered (often in moderate numbers) during the daytime and are easily flushed from low growing vegetation, where they often rest.
