Dogwood (Cornus)-Flea beetle

Dogwood flea beetle (Altica corni)

Pest description and damage Adults of this pest of red osier dogwood are dark, shiny blue, and about 0.25 inch in length. Larvae are black and about 0.25 inch long at maturity. Adults chew holes in leaves while the larvae feed in groups and skeletonize foliage of red osier dogwood. They are capable of defoliating shrubs, but often they are found in smaller numbers throughout the shrubs. Because red osier dogwood is abundantly planted in riparian zones there is a potential for buildup in these settings.
