Behavior
Adult insects are nocturnal. Like other root weevils, they often wander into households during hot summer months in search for shade and moisture. Although harmless to humans, pets and furnishings, they pose a nuisance.Food
Larvae feed on plant roots, while adult insects feed on leaves, eating only the edges in form of numerous U-shaped notches. They are commonly present on North American lilac, but seldom create lasting damage to the plant.References:
