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.

Subject: rose borer wasp?

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.

Subject: Wasp or Hornet?

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.

We saw this bright yellow eyed fly in November near Kimberley, South Africa.
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
TdW

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

Subject: Shower Wasp?

It’s December in Texas, and this flying bug (and lots of its relatives) has recently shown up in our shower. We see about 2-4 a day. The shower has an exterior wall, but we can’t find any holes around the tile or windows. It doesn’t seem to be aggressive, but it does look like a stinger-type body. Ideas?

Ed. Note:
We did not recognize this wasp and we thought the situation was odd, so we contacted Eric Eaton with the following.
Hi Eric,
Happy New Year.
This Wasp is from Dallas Texas.  The person keeps finding them in an  indoor shower with an outside wall.  They find two to four a day.  This does not look like a social wasp to me.  Can you identify at  least family and possibly species?
Thanks
Daniel

Hi, Daniel:
Happy New Year to you, too.
This wasp is not a social wasp, but a solitary one in the family Crabronidae, tribe Larrini.  It *might* be Tachytes or Larropsis for genus, but they are difficult to determine to genus without having the specimen in hand.  Don’t know why they are emerging indoors at this time of year, but they are *not* harmful.
Eric

Dear LN,
We sought some assistance from Eric Eaton with your request and his response is included.  According to BugGuide, the Square Headed Wasps in the subfamily Crabroninae:  “nest in hollow stems or in abandoned galleries in wood, others burrow in the ground. Prey is mostly flies, but some utilize other insects.”
  If you have sash windows, they might have emerged from a nest in the windowframe due to the warmth indoors.

I took this photo, in Sequoia NP, California, completely by accident! I was trying to photograph the Butterfly! Does anyone know which species of Wasp it is?

Sand Wasp

Sand Wasp

Hi GaryT,
This appears to be a Sand Wasp in the tribe Bembicini, but we are uncertain of the species.  It appears to us to resemble members of the genus
Steniolia that are pictured on BugGuide.

Thank you very much for your really quick response. This at least gives me a starting point to look a bit deeper.
Thanks again

Let us know if you get a more specific identification and we can update the posting.
