Pink-edged Sulphurs are northern butterflies that are much more at home in the woods than their relatives, Orange and Common Sulphurs, that prefer more open areas. This species has but a single brood and may be found from early June through August. Its chief larval foods are blueberries.
Identifying characteristics: Above, the wings are yellow with black marginal borders. The males have a solid black border and look very much like the Common Sulphur, while the females have a much-reduced border on the front wing and a no border on the hind wing. Below the wings are a yellowish color and a single central spot.
Similar species: Clouded Sulphur males are very similar, but below the Pink-edged Sulphurs lack the faint row of black marginal spots and they have just a single central spot.
