Western White-ribboned Carpet Moth

Mesoleuca gratulata, the Western White-ribboned Carpet Moth, is an early-flying day moth. The moth breeds from California to Colorado, north to southern British Columbia and Alberta. They lay eggs in the early spring. Caterpillars hatch ten days later and over-wintering pupa develop in about three weeks. The pupa emerge the next spring. The species is “a sure sign of spring in the west” (bugguide.net). On 3 May 2019, Erika and I photographed this moth at Grass Lake Preserve about a mile from our house in Olympia, Washington.
