The Black and Yellow Mud Dauber is a species of solitary wasp scientifically known as Sceliphron caementarium.
Commonly found across various regions, these wasps are known for their distinct appearance and unique mud nests.
Known to be non-aggressive, they are dark with metallic hues and thin waists, often spotted hunting spiders to feed their offspring.
Female Mud Daubers create their nests from mud, each cell containing a single egg.
To provision their offspring, these protective mothers collect up to 25 live, paralyzed spiders per cell.
Despite their slightly intimidating appearance, these wasps rarely sting unless threatened, rating just a 1 on the pain scale which ranges from 1 (mild) to 4 (severe).
Black and Yellow Mud Dauber Overview

Common Habitats
Black and yellow mud daubers can be found in various habitats, such as:
- Meadows: BYMDs are often seen in open meadows where they have easy access to mud and spiders, their primary food source.
- Gardens: They can also be found in gardens where the abundance of insects and spiders provides a steady food supply.
These wasps are known for building their nests from mud in different types of locations, including:
- Walls and ceilings of buildings: They often use sheltered areas where their nests can remain safe from weather elements.
- Vegetation: Some nests are built in vegetation or abandoned cavities, providing them with a more natural habitat.
Overall, the black and yellow mud dauber is a widely distributed wasp that adapts to various habitats within its geographical range.
Life Cycle and Behavior
Nesting Habits
Black and yellow mud daubers (Sceliphron caementarium) are known for their unique nesting habits.
They construct their nests using mud, which are often found in sheltered areas such as under rock ledges, on vegetation, or even on man-made structures.
These nests can take different forms, such as globular or organ pipe-shaped.
- Globular nests: built by the black and yellow mud dauber, containing one cell per nest
- Organ pipe nests: built by the organ pipe mud dauber (Trypoxylon)
Reproduction and Development
The life cycle of the mud dauber begins when a female lays a single egg in each cell of her nest.
She then provisions the cell with paralyzed spiders, which serve as food for her developing larva.
In spring, the larva hatches from the egg and feeds on the spiders. As it grows, it will eventually pupate and develop into an adult mud dauber.
Feeding Habits
Mud daubers have a diverse diet, targeting a variety of spiders as prey. Some common spiders they prey on include:
- Crab spiders
- Widow spiders, including black widows
- Orb weavers
In addition to spiders, adult mud daubers also feed on nectar and honeydew, a sweet substance produced by aphids, to sustain themselves.
This sets them apart from other wasp species like paper wasps, which typically do not consume nectar.
Human Interaction and Other Interesting Facts
Effects on Human Environments
Black and Yellow Mud Daubers often build mud nests in various human structures, such as eaves, garages, attics, and barns.
They are not typically aggressive towards humans. Yet, their stings can be painful and can cause discomfort, with their venom primarily meant for paralyzing prey1.
Their presence can also be beneficial, as they control spider populations by paralyzing them and feeding them to their larvae2.
Fascinating Trivia
Here are some interesting facts about Black and Yellow Mud Daubers:
- Their thin legs and elongated body are designed for capturing their prey, mainly spiders2.
- They have large eyes that help them locate and identify their prey efficiently.
- Related species include the Chalybion californicum (blue mud dauber) and the Trypoxylon politum3.
Comparison between Mud Daubers and other Wasps:
| Feature | Mud Daubers | Other Wasps |
|---|---|---|
| Color | Black and yellow | Various colors |
| Nest construction | Mud nests | In vegetation/cavities |
| Prey | Spiders | Other invertebrates |
| Aggression | Low | Varies |
Conclusion
In conclusion, the Black and Yellow Mud Dauber (Sceliphron caementarium) is a solitary wasp renowned for its distinctive appearance and unique mud nests.
While they might appear intimidating due to their vibrant coloration and hunting habits, they are generally non-aggressive towards humans.
Females meticulously construct their nests from mud, each containing a single egg, and provision them with paralyzed spiders as food for the larvae.
These wasps play a crucial role in the ecosystem, controlling spider populations.
Their presence in human environments, such as buildings and gardens, can be intriguing and beneficial.

I don’t write many responses, however i did some searching and wound up here Organ Pipe Mud Dauber Nest – What’s
That Bug?. And I do have a couple of questions for you
if it’s allright. Could it be just me or does it give the impression like a few of these responses look as if they are left by brain dead visitors? 😛 And, if you are posting at additional places, I’d like to follow anything fresh you have to post.
Would you make a list of all of your shared pages like your Facebook page,
twitter feed, or linkedin profile?
What’s That Bug? keeps our limited staff very busy and we don’t have time to post elsewhere. We do not like to judge our readership too harshly. One of the reasons many folks write to us is that they know nothing about insects, but they are curious nonetheless.

Check this out, there’s a video here: https://www.shutterstock.com/pt/video/clip-16072627-stock-footage-four-yellow-wasps-stacked-on-top-of-each-other-mating-hd.html?src=search/B5DfpkfH9o-BELGCykGv8g:1:64/gg

Wow. Thanks for both links Cesar. We will update the posting.
I took pictures of something just like this, shortly after I took the pic they all were dead.
Hi my name Is Jodie I was just wondering if mud wasps are found in. Asutrailia can you please send me some infomation on them please i have two cats and one of my cats likes to play with insects I think he got stung by one of these
The Brisbane Insect site has information on Mud Daubers from Australia.
It’s not the write information I was after it was on the bluee green wasp
I found eight of these gray mud nests inside and on my boat trailer drum brake back plate. There is an extremely small space between the drum and the back plate for the insects to get thru yet they got in and formed a nest and hopefully were able to get out.
Witnessed this a few weeks ago in tx. Today, Approached 4 stacked that fell from sky (almost as soon as they hit the ground). All four scattered and flew off, alive. Mating was my first guess, but I didn’t understand exactly what was going on until I found you guys.
Glad we could assist.
Like the poster, I never want to cause harm to any living being. My question is about the black and yellow Mud Daubers who come into our Venice Beach home (doors always open), and make nests on the back of pictures hung on our walls? I no longer peek behind the pictures, rather just assume nest(s) are being built when I see the (real focused) female in a room in our house. The question is about the offspring- how many, how small, and their safe exit once born? Once in a great while, we close most our doors at night; will they be led out by Mama the next day?
The young will remain in the nest until they emerge as adults, at which time they will likely be found near doors and windows as they try to get outside.
I’ve removed these nests from my stucco using a scraper that you would typically use for removing ice from your car windshield. I have been bitten by a wasp on my front lawn with no provocation, so I remove them by first spraying with wasp spray, then scrape with scraping tool.
