Corn Flea Beetle: Kentucky Corn IPM

Corn Flea Beetle


Corn flea beetles are very small, shiny, round, black/brown beetles that jump readily when disturbed.


These beetles are leaf feeders. They make small feeding scars on the surface giving leaves a gray, frosted or bleached appearance. Damage is generally serious on plants less than six inches tall. Flea beetles also may transmit Stewart's wilt or bacterial leaf blight on field corn. This is of particular concern during cold, wet conditions that favor development of the disease.
