Spotted Grapevine Beetles Are Active Now

News Article

As mentioned in the Clinic Update now is the time to find some of Iowa's largest insects. See the photo below for one example sent by Dennis Molitor, Carroll County Extension Education Director.

The spotted grapevine beetle is a large member of the Junebug family. It resembles a light tan Junebug. It is 1 inch in length and has 6 small black dots on the wing covers. The adults feed on grape foliage but are not usually a significant pest. The larvae are huge white grubs that live in well-rotted stumps and logs. Adult beetles found on grapevines need only be handpicked and discarded.
