🪲 July Garden Pest Series – Day 6 Meet the Japanese Beetle: The Metallic Muncher That Can Skeletonize Your Plants
You step outside and notice your bean leaves look like they've been turned into lace. Your roses have ragged petals. Your basil suddenly has holes everywhere. Then you spot them—shiny metallic green beetles with copper-colored wings, happily feasting on your plants. Meet the Japanese Beetle, one of the most recognizable (and frustrating) garden pests of summer. The good news? They're easy to identify. The bad news? They rarely travel alone. 𝐖𝐡𝐚𝐭 𝐀𝐫𝐞 𝐉𝐚𝐩𝐚𝐧𝐞𝐬𝐞 𝐁𝐞𝐞𝐭𝐥𝐞𝐬? Japanese beetles are about ½ inch long with a brilliant metallic green body and coppery-bronze wing covers. Along each side of their abdomen are small tufts of white hairs, which help distinguish them from other beetles. Adults emerge from the soil in early summer and immediately begin feeding. They often gather in groups, and once a few beetles find a favorite plant, many more usually follow. 𝐖𝐡𝐚𝐭 𝐃𝐨 𝐓𝐡𝐞𝐲 𝐋𝐢𝐤𝐞 𝐭𝐨 𝐄𝐚𝐭? Japanese beetles have a huge appetite and feed on more than 300 kinds of plants. Some of their favorites include: 🌹 Roses 🍅 Tomatoes 🫘 Green beans 🌿 Basil 🍇 Grapes 🍓 Strawberries 🍎 Fruit trees 🌺 Hibiscus While they can feed on many ornamentals, vegetable gardeners often notice them first on beans, basil, and roses. 𝐇𝐨𝐰 𝐭𝐨 𝐒𝐩𝐨𝐭 𝐓𝐡𝐞𝐦 Look for: ✔ Metallic green beetles with bronze wings ✔ Leaves that look "skeletonized," with only the veins remaining ✔ Ragged flowers and petals ✔ Groups of beetles feeding together ✔ Chewed fruit and foliage Unlike many pests that hide, Japanese beetles feed right out in the open. 𝐖𝐡𝐲 𝐓𝐡𝐞𝐲'𝐫𝐞 𝐚 𝐏𝐫𝐨𝐛𝐥𝐞𝐦 A single beetle isn't usually a major concern. But dozens feeding together can quickly: • Skeletonize leaves • Damage flowers • Reduce photosynthesis • Stress young plants • Reduce vegetable and fruit production Their feeding also attracts more beetles, making early action especially important. 𝐇𝐨𝐰 𝐭𝐨 𝐆𝐞𝐭 𝐑𝐢𝐝 𝐨𝐟 𝐓𝐡𝐞𝐦 The sooner you begin controlling them, the better. ✔ Hand-pick beetles early in the morning when they're sluggish. Be careful not to crush the beetles when removing them, as this can release pheromones and attract bigger populations to your yard.

They have committed murder to my roses and hibiscus. I have pictures, but can’t find them now of my roses with them on my blooms. This is a hibiscus with the leaves destroyed. .

Retired, loves to grow roses, hydrangeas or any flower that blooms. I don’t know what I’m doing; I plant water and feed and hope for the best.
