Grape flea beetle

Altica chalybea

Grape flea beetle

Eric Burkness, University of Minnesota

Size: 15 inch long

Description: Oval-shaped, shiny blue-green body.

Where/When: Feeds on buds of wild and cultivated grapevines and Virginia creepers (the larvae feed on leaves). Active from late April to early June and late July through August.

Significance: Tunnels into buds in spring, damaging them. They are generally not common and damage is typically not important, although they can become numerous in localized areas, causing significant damage and reducing yield. Leaf feeding in late summer is not important.
