CENTRAL FLORIDA CRITTER OF THE DAY: Cloudless Sulphur (Phoebis sennae)
The cloudless sulphur is a rather large butterfly easily seen because of it’s bright lemon color. My observations indicate it is particularly fond of red flowers, although I see it often on Bidens alba.
Butterflies are attracted to most flowers for nectar including this Coral Honeysuckle.
If you want increased populations you need to provide host plants for the caterpillars. In my garden that is Partridge Pea (Chamaecrista fasciculata) for this species.
