I was lurking around my butterfly garden this morning and happened to see this small wasp (Eumenine maybe?) subduing a large syrphid. Amazingly, the wasp took off with her prize with seemingly little effort!

Square Headed Wasp preys upon Hover Fly

Good Mornind Deborah,
What an amazing image.  This is a Square Headed Wasp in the subfamily Crabroninae, and we believe that based on this image from BugGuide, that it is in the genus
Ectemnius.  According to BugGuide:  “most nest in decayed wood (logs, stumps), sometimes in sound wood; provision the nests with Diptera.”   The prey appears to be a Drone Fly.

It’s fairly easy to tell this is a Sand Wasp given the shelter and size. Finding out that they are not aggressive to humans AND they feed on flies means this little guy(gal) gets to stay right where he(she) is. July 12, 2016, West Valley City, UT.

Sand Wasp

Sand Wasp

Dear Vic,
Thanks for sending in your image of a Sand Wasp in the tribe Bembicini in her nest.  We don’t think we will be able to provide a species identification based on this image.  According to BugGuide:  “About three quarters of the species prey on Diptera, and it is believed that fly predation is ancestral in the group; the rest prey on Lepidoptera, Hymenoptera, Neuroptera, Odonata, and/or Homoptera.”

Western Cicada Killer Carnage

Western Cicada Killer Carnage

Dear Tracey,
No insect winds up on our Unnecessary Carnage page more than the Eastern Cicada Killer, because these solitary wasps are large and frightening looking, however they are not aggressive, and though a female is capable of stinging, they do not seem at all interested in stinging people.  You have submitted an image of the Eastern Cicada Killer’s western cousin, the Western Cicada Killer, and we don’t generally get Unnecessary Carnage images of the Western Cicada Killer because we just get far fewer images of them.  Like the eastern cousin, the Western Cicada Killer is a solitary wasp and it is not aggressive.  It was likely searching your trees and bushes for Cicadas because female Cicada Killers sting and paralyze Cicadas, and then drag them back to the nest they have constructed underground.  The female lays an egg on the paralyzed Cicada which then acts as food for the developing larva.

Started off with one in the wall by my driveway and now there are dozens flying around. It is a duck wall with dirt. They dig into the wall and hang out around the wall during the day”fighting” eachother. What are they? Yellow jackets, hornets, some other singing bug?
Thanks, want to get rid of them if they attack since have small kids who miss riding their bikes in the driveway.

Dear Jenngi,
Though male Cicada Killer wasps are quite territorial, they are incapable of stinging. They are very specific about preying upon Cicadas. Female Cicada Killer wasps are not aggressive, and we have yet to receive a report from someone being stung by a Cicada Killer.  In our opinion, they do not pose a threat to your children.  This is our first reported Cicada Killer sighting of the year and we are saddened that it is a dead individual.  We would urge you to educate your children about the natural world around them so that they can appreciate and respect the lower beasts.

Thank you for your quick reply. Now we can watch these awesome creatures, have about 15 now, without the fear of multiple settings. It is a relief to hear that these are not aggressive stinging wasps or hornets and will not be creating a nest of thousands so close to our entry into the house and where we play. The kids love and respect all creatures big and small. We strive to live in peace with creatures. Thank you again for the reply.

Thanks for getting back to us Jenngi.  As further clarification, only social wasps like hornets, yellow jackets and paper wasps will defend a nest by stinging.  Solitary wasps like Cicada Killers do not defend the nest.  Though they sometimes nest in colonies where soil conditions and hunting prospects are ideal, Cicada Killers are solitary wasps.  Again, male Cicada Killers will defend territory, especially against other male Cicada Killers, but only females have a stinger which is used to paralyze Cicadas to act as food for the developing young.  Cicada Killers appear in the summer and the larvae that are developing in the subterranean nest will not emerge until the subsequent summer.  Cicada Killers females are capable of stinging, but we believe this will only occur if they are handled.

How long are cicada killers active? First one appeared about a week ago and now there are about 15-20 in the wall right by my driveway. Are they out  all summer? Also do they kill bumblebees too?
Signature: Jenngi

Cicada Killers do NOT prey on Bumble Bees.  You should expect activity for about four to six weeks, during which time females will hunt Cicadas to provision the nest for the developing young.

based on some peoples opinions, I believe this might be Trypoxylon, but I wanted to here your opinion on it as well.
Thank you!

Square Headed Wasp

Dear Cicada Lover,
We believe that this is a Square Headed Wasp in the subfamily Crabroninae which is well represented on BugGuide.  Though the subfamily contains the genus
Trypoxylon, we cannot state with any certainty that is the correct classification.  Perhaps one of our readers will supply additional information.
