Observation notes: First butterfly of the year. The only one observed. Morning was at or near freezing. Day warmed up into the high 50's or low 60's. Break in the many rainy and cloudy days. Earliest Margined White that I've seen in Mendocino County. Male. Didn't stick around for a photo of the underwings.
