Palestriped Flea Beetles are a pest of many food crops, and can also cause damage to ornamentals, particularly when the host plants are young.


Adult beetle is yellow through brown or black with a paler stripe on each wing cover, and a red head. Like all Flea Beetles, they jump away when disturbed. Grubs are long and thin.

Symptoms and Signs[edit]

Grubs cause root damage, particularly to tubers such as potatoes or sweet potatoes. Adults cause shotholing or skeletonized leaves, particularly of young plants.
