Butterflies and moths are accidental pollinators of many flowering plants. While most species do not have special structures to carry pollen, they do brush against pollen and transfer it to other flowers.

Did you know? The Eastern Tailed-Blue (Cupido comyntas) flies close to the ground and uses its short proboscis to probe flowers of wild strawberry, white sweet clover, and other low-lying plants.
