Even if you don’t know what a Japanese beetle is, you probably know what they look like. The shiny green-and-bronze beetles are one of the most common–and frustrating–lawn pests in the US. Every summer, they show up in droves to feast on virtually every tree, plant, and bush they can find. They’ll even chew straight through flower bulbs!
Here’s everything you should know about your summer nemesis–including how to keep them from destroying your yard this year
Japanese beetles (Popillia japonica) are an invasive beetle species distributed throughout most of the eastern and central US. Adult Japanese beetles are small (⅓-½” long), with green heads and metallic-looking, copper-colored elytra (wing covers). Their exoskeleton has a distinctively iridescent or metallic look and often catches the sunlight. Adult beetles also have six white tufts of hair sticking out from either side of their lower abdomens. Did you know, for instance, that Japanese beetles live most of their lives as grubs under the soil? They fatten themselves by eating the roots of your grass and that’s also when they are most destructive. They are sometimes called “white grubs” because of their pale, creamy orange or white coloration. Their heads and legs are darker than their torso and abdomen, which can appear almost translucent. Japanese beetle grubs are normally around one inch long. They often bend their backs and curl forward, giving them a “C-shaped” appearance. Grubs live underground until adulthood, where they can feed on root systems. Larvae may darken as they grow and feed.
The beetle inflicts economically significant damage on lawns, crops, and gardens. They’re known to feed on over 300 different plant species. Grub and adult beetle stages do different kinds of damage. Grubs chew through grass and ornamental plant roots from underground, reducing the plant’s ability to effectively absorb water. Adults “skeletonize” the leaves of many plants by chewing away leaf tissue but leaving behind the fibrous structure. Japanese beetles feed on a wide variety of plants, including many very common lawn and garden plants. You’ll commonly find them on linden, maple, oak, birch, elm, and willow trees, among others. They’ll also damage fruit such as apples and raspberries, vegetables such as corn and soybeans, and more. They’re considered a serious agricultural pest. Grubs can also inflict serious lawn damage by swathes of turf grass, leaving behind yellow, dead patches. Grubs feed underground and out of sight. They don’t really care if your grass dies in the process.
