Grapevine beetles are common in the north and central United States and eastern Canada, but do relatively little damage to their host plants.

The adult beetle is approximately 2.5 centimetres (1 inch) long, but can reach 3 cm (1.2 in) occasionally.

Adults in the northern parts of its range will have darker and more spots, while those in the southern regions may not have them at all.

[citation needed] The adult beetle eats the leaves and fruit of grapevines, both wild and cultivated, although it is not normally a major pest of vineyards.

They lay eggs in rotten wood, tree stumps, or on soil near the host plant, where they hatch into larvae, which may grow up to two inches long.
