These beetles display shiny, iridescent green bodies with coppery-brown wing covers, making them the fashionistas of the insect world! With their dazzling appearances, it's hard not to admire these delightful invaders.
Japanese Beetles are hungry munchers with a taste for over 300 different plants. They love to snack on leaves, flowers, and fruits, turning gardens into their personal buffet lines.
