Stunning in their metallic shades of vibrant copper and emerald green, Japanese Beetles might seem like welcome immigrants to our state. However, anyone who has lived in other parts of the country knows how destructive these voracious scourges can be. Until recently, Japanese beetles were unknown in Colorado. Unfortunately, they are now prevalent both in southern Denver and in locations along the Western Slope. It is only a matter of time before they spread southward to El Paso county. Gardeners here can prepare by learning how to identify these beetles and protect their landscapes.
