Subject:  Grass Carrying Wasp from France
Location:  southwest France
August 1, 2017
Hi Daniel,
Continuing the theme of the grass carrying wasps, there are 3 or 4 of them nesting in the hollow section frame of our aluminium table on the terrace here in south-west France.
They are quite active at the moment and I promised you a photograph if I could get one. Herewith attached.
Sadly, I have missed two great opportunities to photograph them – once bringing in a long piece of grass for the nest and  the other a day or two ago flying in with a young cricket under its ‘fuselage’. Would have been great shots bout just couldn’t get the camera to hand in time. The do seem to be still nesting and feeding so I will do my best to capture this for you sometime and let you have the images.
Whilst writing, I have also attached an image of a spider’s web the like of which I have never seen before. It is fully round in shape (I.e. globe / ball shaped) and  abot 2 ½” – 3” diameter, with what I presume to be the owner sitting quietly in the centre awaiting the arrival of its latest prey. It is on the outside of a window, placed in the angle of the frame and the stone wall. Any ideas on what sort of arachnid this may be?
Kind regards,
Robin

Grass Carrying Wasp

Dear Robin,
Because your original submission did not include an image, we posted it as an update to our Bug of the Month for May 2017 posting on Grass Carrying Wasps, but the addition of this image warrants its own unique posting.

These “things” are adhering to the stucco on the outside of the house. They are very hardy. No amount of hose spray will bring them down. I have eliminated other things like wasp nests before. Never seeing anything like this.

Mud Dauber Nest

Dear Bugged in California,
This looks to us like a Mud Dauber Nest.  Mud Daubers are beneficial wasps that are not aggressive.  There is no need to hose it away.

Grass Carrying Wasp

Dear K & D,
Your images are of a Grass Carrying Wasp and the nest of a Grass Carrying Wasp.  Grass Carrying Wasps frequently build nest, according to BugGuide “These wasps commonly make their nest in the narrow track found above outer windows.”  Grass Carrying Wasps are not aggressive, and if the nests are in a location that permits the adult wasps to escape once they emerge, we would suggest you just leave them alone.  Most of the images of Grass Carrying Wasps we have on our site are freshly made and newly provisioned with Tree Crickets.  Your nest was built last season and contains the pupae of the soon to emerge adult wasps.

A most unusual hornet looking bug was in the area while I was working and I have no idea as to what it is. The main body was orange and black and legs were orange as well. It would be great to know what this is and possibly where it comes from as I have never seen anything like it in this area.
Thank you.

Great Golden Digger Wasp

Dear Jerome,
The Great Golden Digger Wasp is a non-aggressive, solitary wasp found across North America.  They are a harmless species.  Unless you found it already dead, we are going to have to tag this as Unnecessary Carnage and we hope you will be more tolerant if you have future encounters with Great Golden Digger Wasps.

I live in Scottsdale, AZ and this nest was not here yesterday. What is it and should I leave it alone? I’m vegan so I will only rid it if it is dangerous! Thank you!

Mud Dauber Nest

Dear Tina,
This is a Mud Dauber Nest, the nest of a non-aggressive, solitary wasp, probably the Black and Yellow Mud Dauber, that is often found near sprinklers and swimming pools where it gathers mud with which to construct its nest.  It appears your nest is at the beginning stages of construction.  Eventually, the female Mud Dauber will add additional chambers and each will hold a developing larva and the paralyzed spiders that will provide its food supply.

We opened up our window on the second storey of our home and found this nest filled with these light green insect resembling a grasshopper. I didn’t think that they made nests so I’m not sure if my assumption is correct or how they would even get there. Any info would be really appreciated.
Signature: Thanks for any info.
