striped flea beetle

The striped flea beetle (Phyllotreta striolata) is a type of flea beetle, which belongs to the subfamily Alticinae. These tiny beetles, typically less than 6 mm long, are known for their enlarged hindlegs that enable them to jump. The striped flea beetle is characterized by a yellow line on each of its wing covers (elytra) and is considered a pest, primarily affecting cabbage and other brassica plants.12

Flea beetles, in general, are significant pests of cultivated plants. Adult flea beetles feed on leaves, while their larvae consume roots. Some species can also transmit plant diseases. While they are called flea beetles, they are not related to true fleas.2
