Systena frontalis, the red-headed flea beetle, is a species of flea beetle in the family Chrysomelidae. It is found in North America. [1] [2] [3] It is named for its red colored head that contrasts its black body. Like other flea beetles, it has powerful saltatorial hind legs specialized for jumping. Like all beetles, this insect is holometabolous The larvae are off white in color, 5-10mm in length, have a sclerotized head capsule and a short posterior protrusion.

It is a common insect pest in the eastern United States. Although its origin is uncertain, S. frontalis is thought to be a native species. It has become a highly destructive pest of ornamental plants in nurseries.
It creates "extensive perforations" in the leaves while feeding on common ironweed, Vernonia fasciculata . [4] It is also known to enjoy hydrangeas. Currently, researchers are looking to better understand its phenology and biology to come up with more sustainable pest management practices than frequent spraying of pesticides.
