Flea beetle injury. Flea beetles are small beetles that jump when disturbed. Flea beetles can be found on a wide variety of plants. However, most flea beetles attack only a few, closely related plant species. Flea beetle injury is most important when seedlings are becoming established or in the production of leafy vegetables.
Injuries are usually minor and easily outgrown on established plants.
Flea beetles are common pests of many vegetable Crops. They occasionally damage flowers, shrubs and even trees. Adult beetles, which produce most plant injuries, are typically small, often shiny, and have large rear legs that allow them to jump like a flea when disturbed. The adults chew many small holes or pits in the leaves, which make them look as if they have been damaged by fine buckshot. Young plants and seedlings are particularly susceptible.
