In this article, we will share all the basic species details about the great golden digger wasp, such as its habitat, what it eats, and so on.
Great golden digger wasps will instantly grab your attention as they have brightly colored bodies and are big in size.
These features can make them look quite intimidating, but should you be scared of these wasps?
Also, are they beneficial to gardeners like many other solitary wasps?
Let us find the answers to such questions in this article.
What Are Great Golden Digger Wasps?
The great golden digger wasps (Sphex Ichneumoneus) belong to the Sphecidae family and the order Hymenoptera.
These insects get their name from the bright golden hairs on their head and thorax. Their abdomen is usually rusty-red or orange in the front and black in the rear.
This vivid combination of colors gives it a catchy and attractive appearance that instantly catches people’s attention.
Also, great golden digger wasps are big insects; they show an average growth of about 1.5 inches.
You must know that these giant insects are solitary wasps; the female wasps prefer to construct individual nests to lay eggs.
What Does A Great Golden Digger Wasp Eat?
Adult wasps mostly have herbivorous diets. They are fond of drinking sweet flower nectar, and you can find them hovering around gardens and wildflowers.
The larvae rely on a protein-rich carnivorous diet to fulfill their needs.
The adult female hunts down pests like crickets and katydids. Fascinatingly, these insects do not kill the prey; they paralyze it to carry it back to their burrows.
The larva then devours the paralyzed insects to gain enough nutrients to start its pupal stage.
The availability of prey and food acts as a significant factor in deciding the ideal locations for building the nest. Let us take a look at where these wasps live.
Where Do Great Golden Digger Wasps Live?
Great golden diggers are found in various regions of Mexico, North America, South America, and Canada.
As mentioned above, these insects prefer to be around flowering areas as they primarily rely on nectar to fulfill their diets.
They like to be around open grasslands in a warm and sunny climate. Also, they build underground nests and prefer to be near sandy soil.
Unlike social wasps, you cannot spot them in big groups. However, nesting aggregations of up to hundreds of females can occur in ideal nesting areas.
Life Cycle of A Great Golden Digger Wasp
The life cycle of great golden digger wasps starts in the early spring when the females prepare to lay eggs.
They start by looking for an ideal spot to build deep underground tunnels. Once she finishes the digging, the entrance is covered to hide the nest’s existence.
She then proceeds to hunt small insects for the young ones.
Once the prey is tracked, the female digger wasp stings it. The stinger does not kill the insects, it paralyzes them.
The paralyzed prey is then carefully carried to the underground, vertical tunnels built by the females.
On their way to the nest, the wasps get ambushed by birds like robins. This is an attempt to steal the hunt from the wasp.
If the wasp manages to get the hunt to the nest, she does not put it in the burrow straight away; she first inspects the east, and if everything is intact, she stuffs the paralyzed prey in it.
She then drops an egg on the same vertical tunnel containing the insect. Once done, she exists and covers the tunnel again.
This process is repeated until all the tunnels are filled with insects.
Unlike social wasps, the great golden digger wasps do not show aggressive behavior in defending the nests.
When the eggs hatch, the wasp larva starts consuming the immobile insect in the chamber.
They devour the entire insect to gain size and nutrition to merge as active and healthy adults in the summer.
How Long Do Great Golden Digger Wasps Live?
Great golden digger wasps live around five to eight weeks as adults.
These insects can die much earlier if they are hunted down by potential wasp predators like birds, raccoons, and other giant insects.
The adults usually emerge during the peak summer months.
Do They Bite/Sting?
Great golden digger wasps may appear scary, but they are almost harmless. The males do not possess stingers and will not harm humans.
The females have stingers, but they use them to hunt insects only.
These wasps will only attack if you try to handle them recklessly. However, their stings can be painful.
Are They Poisonous/Venomous?
Great golden digger wasp stings are venomous enough to paralyze small insects, but it is quite ineffective against giants like humans.
However, if you are allergic to wasp stings, you must stay away from these insects, or you will have significant problems.
Are They Harmful or Beneficial to Humans?
As mentioned above, these insects are not harmful to humans. They will only attack if you are reckless around them.
Golden digger wasps are beneficial insects as they help to eliminate garden pests like grasshoppers.
These insects are decent pollinators. Also, by creating underground nests, they increase the aeration properties of the soil.
What Are Great Golden Digger Wasps Attracted To?
Great golden digger wasps prefer open grasslands. They prefer to be around sandy soil, which allows them to effectively build underground nests.
Also, you can find them hovering around flowers for nectar.
You must note that great golden digger wasps are significantly attracted to warm climates.
How to Get Rid of Great Golden Digger Wasps
Great golden digger wasps prefer to be in spaces with abundant pest populations.
They hunt insects like grasshoppers to feed the young ones. If your garden is free from pests, these insects will refrain from digging nests in that region.
Also, since they construct underground nests, they are attracted to loose, sandy soil.
If the garden is filled with grass and other plants, the soil becomes firm, which makes it harder for these wasps to build underground nests.

This article gives you a good overview of the great golden wasp.
Apart from the appearance, nesting habits, and life cycle, we will share a few more interesting facts about these insects in this section.
- Great golden digger wasp females are comparatively bigger than males. Also, the males do not possess a stinger.
- Every mama golden digger wasp inspects the nest before putting the paralyzed prey in it. If the prey gets dislocated while inspecting, the wasp will relocate it, carry it to the nest, and inspect it again before stuffing the hunt inside.
- While putting the immobilized insect in the tunnel, the female always stuffs them head first.
- While carrying the insects to the nest these wasps are ambushed by birds like robins to steal the prey.

Hi,
I live on the same latitude as James but farther west; in Kemptville, ON, half way between Ottawa and Ogdensburg, NY.
I’ve never seen the Great Golden Digger Wasp before but I have at least 3 of them burrowing in my yard. The soil is very sandy and their burrow gets about half a day of sun.
Are these rare creatures? Are they moving North as the planet warms up? Is there anything I should be doing to encourage them?
Thank you,
K
Are these a threat to young children or older adults?
To the best of our knowledge, the Great Golden Digger Wasp is not an aggressive species, and we have never heard of anyone getting stung by one.
I have several holes in my yard and I have only seen 1 wasp looking bug emerge from one hole it looks like the above pic from Sue how ever I have not been able to take a picture of it as I am terrified but I have taken pictures of the holes and they do do just like the about pic. Does this wasp make several holes? I can count at lease 15 holes.
There is one burrowing in my flower garden. It knows I am watching but flys away if it feels threatend.I am in Crete Township Will County Illinois
Hello. Nice website. I’m surprised that nobody has made a comment about the buzzing noises the golden ground diggers make. I observed one for a while. When it was first digging it’s hole it made the buzzing sound all the while that it was actually pushing into the ground. Later on, when it was covering over the hole ( I missed it putting an egg and bug in) it again made the buzzing sound when it was pushing small debris into and around it’s burrow. This has led me to ponder whether it is using it’s loud buzzing with (I’m sure it’s bodily vibrations) as a sort of “impact tool” It buzzed constantly while it was pushing the debris in place over the burrow opening. It pushed the debris for a solid 8 to 12 seconds, even though you could no longer see the piece of debris moving anymore. Check it out next time you witness one at work. Bloody marvelous. A built-in impact tool. I am positive that is exactly what it was using the buzz for. Way cool!
