All the above photographed in Mill Hill/Totteridge, NW London: considerable variation in the pale spots' size and colour (white, cream, very pale yellow, pale pinky-yellow)

 and in the size and "openness" of the black spots. Females have brighter and sharper markings than males.

The Speckled Wood butterfly likes sunny clearings in shady woodland and aphid honeydew rather than flower nectar
