Clouded Sulphur

Open areas including fields, lawns, meadows, gardens, and roadsides throughout North America.

Adults feed on flower nectar from various plants including dandelion and milkweed; larvae feed on legumes like clover, vetch, and alfalfa.

Active from spring to late fall; males engage in 'puddling' at damp soil to obtain minerals. They have multiple generations per year and overwinter as caterpillars.

Benefits the ecosystem as an important pollinator; larvae can sometimes be minor agricultural pests in alfalfa fields, but they pose no risk to humans.
