The adult beetle is approximately 2.5 centimeters, but can reach 3 cm occasionally. Its pattern is off-yellow or auburn red, with three black spots running down each side. Fine black lines divide the edges of its elytra.
It lives, like many beetles, in forests, thickets, and woods, and is mostly seen during the summer. Active flyers, these beetles are commonly attracted to lights at night. It is also seen in vineyards and gardens. The adult beetle eats the leaves and fruit of grapevines, both wild and cultivated, although it is not normally a major pest of vineyards.
