Steel Blue Cricket Hunter

Dear Kat,
This is not a Beetle.  It is a Steel Blue Cricket Hunter,
Chlorion aerarium, a Wasp in the family Sphecidae.  According to BugGuide:  “Although generally not closely associated with humans, they are found wherever their hosts (Gryllus crickets) are found, which could include close proximity to homes.”  We believe “3+ inches long” is an exaggeration, as BugGuide states:  “~25 mm.”

Thread-Waisted Wasp

Dear Paul,
This is a Thread-Waisted Wasp in the family Sphecidae, but we are having trouble identifying its species.  It looks similar to individuals in the genus
Sphex pictured on BugGuide, including the Great Golden Digger Wasp, but its abdominal color and white facial and thoracic markings are quite different.  Perhaps one of our readers will provide assistance.

Thanks! I found a Sphex habenus that was close but am not 100% on that ID.

That is the same species that Cesar Crash commented regarding.

Your letter to the bugman:  Found this guy in my apartment, tried to get him to an open window but got spooked when he flew at me. I looked up other wasps in the area but none of them seemed quite right.

Great Golden Digger Wasp Carnage

Dear Hbb,
The Great Golden Digger Wasp is not an aggressive species, and what you mistook for aggression was likely it desperately trying to get back outside.

Your letter to the bugman:  These two were battling it out, but the wasp won in the end. I thought it may have been a cicada killer, but this one was all black, maybe a little Blueish.

Great Black Wasp and Katydid Prey

Dear Karin,
We are thrilled to be able to post your wonderful images of a female Great Black Wasp and her Katydid prey.  The wasp has stung and paralyzed the Katydid and she it trying to get it back to her underground burrow.  She is probably climbing the table to give her some height so she can take off and glide toward her nest.  According to BugGuide:  “Provision nests (in burrow in soft earth) with Katydids or grasshoppers. ”  Also commonly called Katydid Hunters, these solitary wasp are not aggressive toward humans.

Your letter to the bugman:  This guy was moving among the flowering herbs at edge of garden this weekend.  He looks formidable with extremely long back legs.   What is he?

Great Golden Digger Wasp

Dear Charlene,
This large, impressive wasp is a Great Golden Digger Wasp, a solitary species that is not aggressive toward humans.  Was it moving among the flowering herbs like it was more interested in the flowers or like it was searching for something?  This is a pollinating species that feed on nectar as an adult, but it is carnivorous, but helpless, as a larva.  The female Great Golden Digger Wasp hunts for Katydids among the foliage and when she locates one, she stings it to paralyze it and then drags it back to her subterranean nest as food for her brood.  We vote “friend.”

Your letter to the bugman: I’m filming in southern Arizona and came across this wasp (?) pouncing on a cricket. It had the most vibrant, cobalt blue coloring, almost metallic in its sheen. It was about 1.5” in length.
So tell me: what’s that bug?!
Sincerely,

Steel Blue Cricket Hunter and Cricket

Dear Tomás,
You had nearly every word in this predator’s name in your letter.  This is a Steel Blue Cricket Hunter,
Chlorion aerarium, and it is a marvelous addition to our Food Chain tag.  According to BugGuide:  “Females mass-provision several serial cells, each containing from 2 to 9 nymphs or adults of Gryllus pennsylvanicus. Prey are transported on the ground, venter-up, with the wasp’s mandibles grasping the antennae of the cricket.”
