Grass Carrying Wasp Nest with Crickets

Dear Sue,
We wish you had a higher resolution image.  We have never seen an image of such a fully stocked Grass Carrying Wasp nest.  Female Grass Carrying Wasps provision the nest with Crickets, especially Tree Crickets.  We had no idea each larva would eat so many Crickets.  We were under the impression that one cell was used per egg.  We will need to research this matter more.  Your understanding of the behavior of solitary female Wasps and their care for the young is correct.  Paralyzing the prey allows the victim to remain alive and fresh as opposed to old and dried out, so if the eggs hatch in several months, there will be fresh food provided for the long dead mother Wasp.  Social Wasps like Hornets have no need to paralyze prey as there are worker Wasps assigned to child care so the queen can just procreate.  Where are you located?

Bald Faced Hornets Nest

Dear Zena,
This looks like the nest of a Bald Faced Hornet in its early stages of construction.  When complete, it will be about the size of a football.  According to Bee Friendly:  “Bald Faced Hornets become active each year in the early spring (March-April) when the fertile Queen comes out of her underground winter den and begins to forage on flies and other insects, including smaller wasps and bees, while she scouts for a nesting site for the coming year. The new colony will typically build up its population, through the Spring and Summer months (May-Sept), to an average number of 700 members. During the cooler weather of the Autumn (late Oct.) the colony will produce short lived male wasps and fertile females that will then mate and seek out hibernation dens for the winter.The entire colony will eventually die off in mid to late November when the prey insects have all disappeared.”  Hornets will not reuse an old nest.  Hornets are social wasps and they will defend the nest.  Hopefully the nest is high enough in the eaves that human movements will not alarm the inhabitants.  They will sting to protect the nest.

Subject:  European hornet ?

Your letter to the bugman :  Found this hornets’ nest at the base of a tree in north Georgia.  The guards at the entrance were all fanning the nest.  I think this is the European hornet but would like confirmation.  Sorry the photos are blurry – actually they are freeze frames from a long video clip.  FWIW I am a Patreon donor to WTB!

European Hornets

Hi Bruce,
Thanks for your patronage.  We apologize for the delay, but Daniel is currently in Ohio for Mother’s Day and the internet here is woefully slow.  These are definitely European Hornets. At first we were not convinced this is a nest because European Hornets and many other Wasps will feed on sap that is oozing from trees.  According to BugGuide:  “Paper nest is built in hollow trees, or in human structures such as attics” so we also concur that this is a nest.

Paper Wasp Nest

Dear Lori,
This appears to be a Paper Wasp nest, probably from the genus
Polistes.  According to the Brisbane Insect site:  “There are different species of Paper Wasps. Those wasps in genus Polistes build inverted mushroom-shaped. They build rather small paper combs nest suspended from a peduncle and not surrounded by an envelope. … They are dark brown in colour with yellow bends on dark brown abdomen. The thorax is black in colour with yellow ‘V’ markings. Their faces are yellow with large compound eyes.” Your image is rather dark and lacking detail, so we would not rule out the genus Ropalidia which is also pictured on the Brisbane Insect site.  Paper Wasps are social wasps that will defend the nest against attack by stinging, and some species might be more aggressive than others, but when they do not feel the nest is threatened, they are quite docile.

Hornet Nest

Dear Yvonne,
We can’t help but to wonder if your ceiling is in Sydney, Australia or Schenectady, New York, or perhaps some other place on the planet.  This appears to be the early stages of a Bald Faced Hornet nest, so depending upon your location, this might be the nest of a related species  If summer just began in the Southern Hemisphere for you, this nest is probably being constructed.  If you are in the grips of a northeastern North American winter, this nest was probably long abandoned.

Thanks.
I live in Tasmania, Australia. It is the size of a tennis ball. I havent touched it to determine if its occupied. Its in a barren shed used as a change room at a local country pool. (So only used in summer). It is suspended from a ceiling joist. There was no activity for the 10 minutes we were in the shed. This was in the daytime
Cheers yvonne
Another suggestion was a polyphamus moth??
Just cant find an exact replica on google images.

Thanks for the clarification Yvonne.  This is not a moth cocoon.

Thanks Daniel. Will keep an eye on it. See what develops. Yvonne

Subject:  Mason Was planning – I think!
Geographic location of the bug:  SE Louisiana

Your letter to the bugman:  Found two of these tiny wasp-looking creatures leaving their baby creatures in tiny perfectly round holes in my shed wall. Got a photo of one but the other flew off before I could get her. I say ‘her’ because she was a bit thicker in the abdomen and I thought that maybe she was carrying eggs. After an Internet search I figured that they are probably Mason Wasps, but I’m wondering if you can tell me more. I’m an avid outdoors person and am astounded that I’ve never seen these before! I’m quite familiar with Carpenter Bees, they like my shed as well. An ID would be appreciated!
Thanks,

Keyhole Wasp Nesting

Dear Margie,
We feel pretty confident that this is NOT a Mason Wasp in the subfamily Eumeninae, as those tend to be bulkier, based on images posted to BugGuide.  We believe this is a Thread-Waisted Wasp in the family Sphecidae, but we would gladly accept any identification assistance our readership can provide.

Keyhole Wasp Nest

Thanks, Daniel! I also posted to the Insect ID page on Facebook. One of the readers there thinks that it is a Crabronid Trypoxglon? He said “Not a potter, mason, mud dauber, or thread waisted.”
What do you think about this ID?
Margie
Hi Margie,
The large head was one of the features we observed, and according to a comment by Eric Eaton on BugGuide:  “All other our species (the ‘keyhole wasps’) nest in pre-existing tunnels like beetle borings, sealing the finished nest with mud. Paralyzed spiders are used as provisions in each cell.”  That seems like a very good identification to us and we like the name Keyhole Wasp.
Hi,
I’m looking at your site and searching under the Trypoxylon group I found this guy – I think it is the same:
Is this one called a keyhole wasp, too?
Margie
Hi again Margie,
That link was from BugGuide, not our site.  The name Keyhole Wasp was used in a comment by Eric Eaton.  When we researched the common name Keyhole Wasp, we found it in reference to the Mason Wasp
Pachodynerus nasidens on BugGuide.
