About

The Japanese Beetle is a scarab beetle with a striking metallic green body and coppery-brown wing covers, ringed by tufts of white hair along the abdomen. Accidentally introduced to the United States around 1916, a single adult can skeletonize a leaf in minutes by eating the tissue between veins.
