Size: Up to 1 3/4 inches long
Where/When: Commonly found on petunias, geraniums, and nicotiana, while occasionally damaging roses and other plants. Active in Minnesota during late summer.
Significance: The larva damages flowers by chewing deep holes into the buds, causing flowers to have large holes in the petals. Tobacco budworms may also eat the flower blossoms, giving them a ragged appearance.
