Clouded Sulfer

Sulphur butterflies are medium-sized, yellow or orange, and frequently have a black border around the wing edges. The Clouded Sulphur is lemon-yellow. Occasionally, females are very pale yellow to almost green.

Clouded Sulphurs are active in the Hocking Hills from mid-spring, throughout summer, and into fall. They prefer open fields and gardens, in both urban and agricultural areas where the caterpillars eat alfalfa and clover.
