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.

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.

Hello, I have recently been studying bugs and have been unable to identify the little bugger you see below. The bug itself seems to hang around the orange coneflower (rudbeckia fulgida) quite a bit and always lands on the outer extensions of the head of the flower before heading to the center portion. Thanks!

Dear Connor,
Your image is not sharp enough to be certain, but we believe this might be a Square Headed Wasp in the subfamily Crabroninae, and it looks similar to this image posted to bugGuide.

Cutting off some sickly stems of my knockout roses, I found the stem (about 1/2″ in diameter) to be hollow inside. I slit the stem lengthwise and found these guys inside. I looked them up using whatever search terms I could think of, but found nothing similar. The wasps (?) are about 1/4″+ in length, and they appeared to be newly “fledged”…just beginning to spread their wings. Perhaps they were about ready to bore their way out, having passed through their larval stage?

Small Carpenter Bees

Square Headed Wasps

Hi Laurel,
We didn’t think these seemed like the usual suspects, Small Carpenter Bees in the genus
Ceratina, so we checked with Eric Eaton.  Here is his response.

Eric Eaton identified Square Headed Wasps
Daniel:
These are square-headed wasps, family Crabronidae, and probably Ectemnius continuus.  They nest in pith like small carpenter bees, certain mason bees….but they stock the tunnels with paralyzed flies as food for their offspring.  So, still beneficial, just in a different way.

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.

Any idea what it is?

Sand Wasp or Fly???

Sand Wasp

Hi Tjeerd,
This looks more like a Sand Wasp than a Fly to us.  We may not have time to research this completely before rushing off to work this morning, but we are posting your photo now and we will continue to research this gorgeous creature when we return to our offices.
  Here is a Sand Wasp image from ISpot.  Those orange legs are sure pretty.  Your photo is gorgeous.

Thanks a lot. You remarks took me to this site: http://www.ispot.org.za/node/207535?nav=parent_ob where the same wasp is shown, a Crabronidaea
Many thanks.
Greetings

Hi again Tjeerd,
And there is a comment with a link to Wikipedia and the indication the genus of this beauty is
Tachysphex.  The Sand Wasp tribe of Bembicini is contained within the family Crabronidae.  We believe the superfamily (if our memory of the endings is correct) Crabronidaea may be an obsolete taxonomy.  Here is the BugGuide taxonomy.

Hello Daniel
Thanks for your help. I notice insects is/are your passion .
Now this wasp knows its place in the hierarchy. So many insects, so many names. Maybe it’s good many many insects have not been discovered yet, your life would be even more complicated.
Greetings
TdW
