Sulphur Butterflies: Phoebis
|More Butterfly Information
The Cloudless Sulphur (Phoebis sennae), the most widespread of the four native Phoebis species, spreads its wings from coast to coast.
While male wing color remains yellow throughout its range, female wing color varies from yellow to white.
The top picture shows a female with a wide band of pink around the wing edges. The crooked line of spots on the top wing differentiates it from the Large Orange Sulphur.
The prominence of the pink band along the wing edges varies from specimen to specimen.
Wing color remains constant for male and female Large Orange Sulphurs (Phoebis agarithe). It's bright yellow, tinted with shades of orange.
Picture two contrasts a male sporting orange shaded wings against a scarlet sage background.
Males usually display less wing markings than females. The straight line of spots across the wing helps identify it.
