It spins a cocoon and remains in the cell until the next spring. The wasp larva hatches in a day or two and grows rapidly while feeding on the cicada, completing development in less than 2 weeks. The female wasp places an egg under a femur of one of the cicada’s middle legs and then seals the cell. The prey can weigh up to three times as much as the predator, so most wasps drag cicadas along the ground and up a tree or other vertical object, from which they can launch themselves downwards toward their burrows. She hunts cicadas, and after locating one, she paralyzes it with her sting and transports it to her elaborate underground burrow. Each female digs burrows 6-10″ deep and oval chambers perpendicular to the main tunnel that hold each of her sixteen or so eggs along with the paralyzed prey. The excavation activities often create mounds of soil in lawns. They then use their forelegs to push the soil under their bodies and their hind legs to expel the dirt from the tunnel. They loosen compacted earth by biting at it with their mandibles. After mating, the females excavate nests in the ground, usually in full sun where vegetation is sparse and the soil is light and well-drained. Adult wasps appear about the first week of June in Arkansas, at about the time when cicadas begin to emerge. They are common throughout the United States east of the Rocky Mountains, in areas where annual cicadas are prevalent. Then about every 17 years, the periodical cicadas surfaces in mass.Cicada killers are large wasps, nearly 1 1/4″ long, resembling large yellow jackets or hornets. Most people I talk to, however, seem reluctant to get that close and would rather kill them off.Īdult dog-day cicadas surface every summer in Michigan. After a month or two, they die. Howard Russell of the Michigan State University Diagnostic Services, Department of Plant Pathology, writes:ĭespite their large size and impressive stinger, cicada killers do not readily sting and one can stand amongst their burrows and watch them work without fear of being stung as long as one remains considerate and respectful, i.e., don’t try and catch one with their hands. This secretive native insect has been here all along, and can be found silencing cicadas across the entire eastern U.S.” “You may see these wasps while you’re outside this year and immediately think of the stories of giant murder hornets invading North America,” DNR game biologist Karen Cleveland says in the newsletter. Just like the cicadas, cicada killer wasps die as summer wanes. While male wasps may be territorial or act aggressively, they lack a stinger and pose no danger to people females sting only in self-defense. Only female wasps have stingers, which they use to inject venom into their prey and carry it back to their burrow.Ĭicada killer wasps are solitary, and female wasps use their short time as adults to dig burrows where they stash the cicadas they catch and lay their eggs. Measuring over an inch in length, these wasps are built to capture and subdue large adult cicadas. The name sounds scary: Cicada Killer Wasps.īut the Michigan Department of Natural Resources assures us in its latest newsletter that the "cicada killer wasps are nothing to fear.'Īs cicadas surface this summer in Michigan, so do the cicada killer wasps.
