Hi there! I’m constantly scanning my outdoor plants for bugs I’ve never seen. I see something new almost every day! I came across this pretty little beetle in the center of a small sunflower. Can you tell me about it? Thanks!
Your beetle is a Spotted Cucumber Beetle, Diabrotica undecimpunctata, and according to BugGuide, the larva is known as the Southern Corn Rootworm. BugGuide also contains this comment: “Considered a major pest of many field crops including cucumbers and other squashes, corn, soy. Beetles also transmit crop diseases such as bacterial wilt. Adults also reported damaging to garden plants including hibiscus, roses.“
