Cicada Killer Wasp

During this week’s Tuesday morning BYGL Zoom Inservice, Curtis Young (OSU Extension, Van Wirt County) reported that he heard the first Annual Cicadas (family Cicadidae) singing in northwest Ohio. Curtis noted they are about 1 week overdue since he normally hears them in his neck of the woods over the 4th of July Weekend. The cicadas are also singing in the southwest part of the state.

Annual Dog-Day Cicadas (Neotibicen canicularis; family Cicadidae) are singing in Ohio. Curtis Young (OSU Extension, Van Wirt County) heard his first cicada on July 3. Dave Shetlar (Professor Emeritus, OSU Entomology) reported hearing his first cicada in central Ohio last Friday and I heard my first cicada song late last week in the southwest part of the state.

Annual Dog-Day Cicadas (Tibicen spp.; family Cicadidae) are starting to sing in southern Ohio. This means their nemesis, Cicada Killer Wasps (Sphecius speciosus), will soon be seen cruising woodlands and landscapes in search of their exclusive prey.

When you read or hear about "Asian hornets," you need to keep two things in mind. First, the "Asian" moniker has been commonly applied to at least three hornet species native to various Asian regions. The second thing to remember is that none of these hornets have been found living in the U.S.

Annual Dog-Day Cicadas are singing throughout much of Ohio. Normally this means their nemesis, Cicada Killer Wasps would be seen cruising woodlands and landscapes in search of their exclusive prey. However, I have yet to see a wasp. Could wet spring soil conditions have reduced their numbers?

I posted a BYGL Alert on July 20 regarding Cicada Killer Wasps (Sphecius speciosus) cruising lawns and landscapes in southwest Ohio.  However, since that time, I've been slammed with reports and questions concerning these "giant wasps."  So, I'm reissuing my cicada killer report; it appears there are some very heavy localized populations.

 

These large wasps are the nemesis of Dog-Day Cicadas (Tibicen spp.), so it is no coincidence that they appear on the scene when dog-day cicadas emerge.  Cicada killers are the largest wasps found in Ohio, measuring 1 1/...
