A strong, fast-flying, far-ranging butterfly and a cheering sight on a warm March day. The males are bright yellow in colour but the females have a yellow with greenish-white colouration and from a distance can be mistaken for the Large White. Both have an orange spot in the centre of each wing. Seen across Yorkshire in parks, gardens, woodland edges, heaths and grassland. Caterpillar food plant is Alder Buckthorn and Purging Buckthorn.
