Japanese beetles are about a centimeter in length, with a dark green metallic prothorax and brown wing covers with rose striations. Identify Japanese beetles, often considered pests, with information from an entomologist and insect specialist in this free video on beetles.
I'm Mike Quinn. I've been a entomologist for twenty years, and we're here at the Lady Bird Johnson Wildflower center talking about what to the, what does the Japanese beetle look like. It's a small beetle; maybe a centimeter in length, and the prothorax in front is a dark green metallic coloration, and the wing covers, or elytra in the back are brown in color with a parallel rose striations. And along the sides there's white tufts, five on each side and two on the back. And this is a scarab beetle, and the larval stage is a white grub which is "C" shaped. And introduced years ago into North America, and they're considered to be a pest species. The metallic green and prothorax, with the green elytra and white spots on the side are a way to ways to recognize the Japanese beetle.
