Black Blister Beetle

Blister Beetles Wreaking Havoc on Tomatoes

I received two e-mails over the weekend from backyard gardeners in southwest Ohio with pictures showing Black Blister Beetles swarming over tomato plants. Black blister beetles as well as Margined Blister Beetles are the two most common species found in Ohio. Both beetles are capable of showing-up in large numbers to feed on the leaves and flowers of a wide range of perennials and annuals including vegetable plants.
