The Minnesota Department of Agriculture (MDA) announced yesterday (July 25) that the viburnum leaf beetle (VLB), Pyrrhalta viburni , has been confirmed in Minnesota in Eden Prairie. VLB is an invasive insect species from Europe and is now found in scattered infestations throughout northeastern U.S. as well as Wisconsin. VLB love viburnum shrubs, especially arrowwood viburnum, American high-bush cranberry, and European high-bush-cranberry. Larvae hatch in early spring and feed on the leaves until early summer. They eventually skeletonize them, i.e. feeding between veins. This damage is similar to the feeding by Japanese beetles. The larvae are yellow to brown in color with many black spots. They grow to almost ½ inch long. Viburnum leaf beetle larvae and damage.

They are active during the summer and into the fall when they chew oval hol
