Click Beetles


Adults are about 0.4 inch (10 mm) long, reddish brown to black, with a prothorax that has pointed posterior tips.

Damage

The click beetle can feed on buds in spring. The injury to the bud looks essentially the same as that of the grape bud beetle. Unlike the grape bud beetle and the cutworm, the click beetle is a day feeder. Over-wintering in the ground litter, it emerges in spring on warm days. Click beetles are often seen in large numbers resting on cover crops during the day. Even with these high populations in the vineyards, they seldom cause economic damage to grapes.

Management

No material is registered for use on this pest; however, click beetles usually occur in conjunction with cutworm infestations and it has been observed that the sprayable materials used for cutworms also control click beetles.
