Just wanted to know the correct name of this bug. On the ground at Lands End, on the Grand Mesa, Grand Junction Colorado. During mid July, did not seem to be aggressive.

Sand Wasp

Dear Paul,
This little beauty is a female Sand Wasp in the tribe Bembicini, but we were not able to match your images to a species on BugGuide.  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.”  The female provisions the underground nest with prey for the developing brood to feed upon, and as BugGuide states, most Sand Wasps prey upon flies.

Since 2013 I’ve been caring for a large rain garden on Faribault County, MN. The pollinators have been late to return, but now I have several of them and of large size, too. I took some photos yesterday and include three below, which to my untrained eye look like wasps. They have never gone after me, even when I’ve been working in the garden, preferring instead to to move from blossom to blossom.
Image 1 is pictured on the leaf of an achemilla plant. I rarely see this wasp, so for me this was a lucky shot.
Image 2 was a surprise close-up. It looks very much like Image 3 along the abdomen but the head is different in color and markings. To my eye the antennae also differ.
Image 8196 is the most common in my garden. These vary in size from small to as big as my pinky. Right now they are in the large range, approaching thumb size. They are are hefty in weight; blossoms droop when they land on them. They seem to favor milkweed and ratibida (yellow coneflower).
There are a couple others I see now and again, such as the the Great Black and a red version of same with black tip on base of abdomen.
Then there’s one with long legs that trail in flight, though I’ve not been able to capture a photo. Again, I feel safe enough in my garden; I do my weeding thing and they do their thing on the blossoms. I wear a hat and long sleeves with gloves, which I think helps.
Can you identify them? Are they native or exotic?
Thank you.

Unknown Wasp

Potter Wasp

Goodness Wanda,
There are at least ten times more words in your request than in most of the phrases we generally receive.  We miss the chatty identification requests from days gone by before everyone was able to connect to the internet with cellular telephones and people began to forget how to write.  Your first Wasp is not something we immediately recognize, though we suspect it is a Potter or Mason Wasp.  It looks very similar to this 
Ancistrocerus adiabatus posted to BugGuide.

Paper Wasp

Paper Wasp

Your second Wasp is a Paper Wasp in the genus Polistes, and a quick glance at BugGuide has us believing it is the Northern Paper Wasp,  Polistes fuscatus.  According to BugGuide:  “Adult P. fuscatus feed mainly on plant nectar. The species is considered insectivorous because it kills caterpillars and other small insects in order to provide food for developing larvae. Foragers collect various prey insects to feed to the larvae. The wasp then malaxates, or softens the food and in doing so absorbs most of the liquid in the food. This solid portion is given to older larvae and the liquid is regurgitated to be fed to younger larvae. (Turillazzi and West-Eberhard, 1996)”

Cicada Killer

Cicada Killer

Your hefty behemoth is a magnificent Cicada Killer, and your indication that there is a significant population of them indicates a ready food supply for the larvae.  Female Cicada Killers sting and paralyze Cicadas to provision an underground nest.  There is one generation per year and where they are found, Cicada Killers make seasonal appearances.  None of your wasps are considered aggressive.  Thanks again for your entertaining submission.  Your rain garden sounds like it has a very healthy ecosystem.

Western Cicada Killer

Western Cicada Killer

Dear Brooke,
This positively gorgeous wasp is a Western Cicada Killer,
Specius grandis.  Though Cicada Killers are not aggressive and we have not gotten any legitimate documentation of a person being stung by a Cicada Killer, the possibility does exist and we imagine a person might be stung if carelessly handling a Cicada Killer.  We get many more identification requests for the Eastern Cicada Killer, and images of Western Cicada Killers are not too common in our archives.

Hi Bugman!
My kids & I are visiting north Texas and we came across this extremely large flying bug. I’m including 2 pics, one for scale.

Deceased Cicada Killer

Dear Curious Traveller [sic],
This magnificent Cicada Killer looks quite dead and we can’t help but to wonder what happened during your encounter to take it from being an “extremely large flying bug” to one that will fly no more.  Cicada Killers are not aggressive and we have never received an authenticated account of a person being stung by a Cicada Killer.

Thanks for the response. My youngest daughter was in my parents’ backyard playing frisbee with her cousins when the cicada killer was spotted. She ran in to get me (terrified), and by the time I got out there, one of her cousins had killed it.
Thank you for your help identifying it. We are better informed now!

I saw a half wasp half bumblebee bodied flying insect today. What is this thing called and what is its potency when stinging.

Cicada Killer

Dear Glf1sse,
Though your image is very blurry, we are quite certain that this is a Cicada Killer, a large wasp that preys on Cicadas.  This is our first posting of a Cicada Killer this year, though we still have two weeks of identification requests to attempt to answer, and there may be an image of a Cicada Killer there.
  We have no confirmed reports of anyone being stung by a Cicada Killer, a non-aggressive species.

I live in Truro, MA. This insect sits on the corner of my deck each morning that it is sunny but not when it is cloudy or in the evenings. It is quite large (over an inch), and stays all day making the deck unusable. I can’t get close enough to spray because it immediately flies and appears aggressive. Can you tell me what it is and if it is really aggressive.
Thank you.

Cicada Killer

Cicada Killer

Dear Bill,
This is a solitary wasp known as a Cicada Killer, a species that preys upon Cicadas.  This is likely a male, and male wasps are incapable of stinging.  He is likely defending territory against other males in the hope of luring a female into mating and digging a nearby burrow.  Female Cicada Killers are capable of stinging, but they are not aggressive.  We would urge you to abandon your attempts to spray this impressive Cicada Killer.  Normally, we get numerous Cicada Killer identification requests each summer, but this summer your submission is the only one we have received.

Thank you Daniel, for your help.  I will not spray.
