Japanese beetle, Popillia japonica, is a common site in Indiana. They feed on more than 250 species of trees, shrubs, crops and weeds. Year to year, their populations can swing from a minor nuisance to a major economic threat. Japanese beetle was first identified in the United States in New Jersey in 1919.
