This early flying, distinctive butterfly has one generation a year and generally flies between March and May. The female Anthocharis sara in the photo is nectaring on Small-flowered Fringecup (see 80.). The dark line at the base of the orange goes across the entire wing on the males, whereas this one just goes a little ways across. Bizarrely, there are more white females in populations that are found nearer the ocean, and there are more yellow, further from the ocean. Tower mustard (Turritis glabra) is one of the known larval food plant.
