Cuckoo Wasp Sting - What To Do? Helpful Tips

Cuckoo wasps are enchantingly beautiful, but beware – the larger ones of this species might be able to sting. Here’s a primer on a Cuckoo wasp sting and what to do about it.

Cuckoo wasps can sting humans, but there is often nothing to worry about unless you are allergic to insect bites.

You can wash the affected area with cold water or put an ice pack on it. However, in case of severe allergies, it is advisable to seek medical care.

If you are looking for more information on what happens if a cuckoo wasp stings you and what to do about it, continue reading.

What Are Cuckoo Wasps?

Cuckoo wasps are tiny but fast-moving wasps that shimmer in beautiful metallic colors.

These parasitic wasps are usually found during summer, looking for a host to lay eggs and drink nectar.

Cuckoo Wasps are solitary wasps; they don’t build colonies or large nests with other wasps.

Worldwide there are more than 3,000 species of these bugs, of which more than 200 species are found in North America, especially in California.

What Do They Look Like?

Cuckoo Wasps have black eyes, legs, and wings. Their bodies glow in bright and metallic blue, green, or purple colors.

For this reason, they are also known as emerald wasps, jewel wasps, or gold wasps.

The metallic sheen of their bodies is still a mystery to scientists, but one reason could be that it helps them attract other insects so that they can lay their eggs on them.

Can Cuckoo Wasps Sting?

Female cuckoo wasps have an ovipositor that extends out of their abdomen. It has evolved from a stinger. However, it does not have the capacity to sting anymore.

They use this ovipositor to infiltrate the mud nests of other wasps. The female uses her ovipositor first to vibrate and hence soften the mud wall and then lays her eggs into the nest.

This is an interesting activity, also known as brood parasitism. Cuckoo wasps share this activity with cuckoo birds, which is why they were given the name.

However, cuckoo wasps go one step further – their larvae feed off the food that the poor wasp has laid out for her own and then kill the host’s larvae and feed on them as well.

But, leaving that little detour aside, the above para answers the question – does a cuckoo wasp sting humans?

Since their ‘stinger’ is only used to insert their eggs and is non-functional otherwise, cuckoo wasps are not supposed to be able to sting humans.

However, some people have reportedly received painful stings from larger species of these wasps.

So, it is best to maintain a distance from cuckoo wasps if you spot one.

Symptoms of a Wasp Sting

Can a cuckoo wasp kill you with its bite? No. Are cuckoo wasps dangerous for you? Still no.

But are cuckoo wasps poisonous? That question is a bit more complicated. Their stinger has venom that transfers to human skin in case of a bite, and this venom can really cause pain!

The pain will subside in time unless you are allergic. We have discussed the symptoms of their bites in all scenarios below.

Normal Reaction

When a cuckoo wasp bites you, it punctures that area of the skin. The affected area develops a white welt which can cause swelling, pain, or redness.

These symptoms can last for a few hours and will go away naturally.

Severe Reaction

The term for a severe reaction caused due to wasp or bee sting is ‘large local reaction.’ It usually results in swelling, redness, and pain, which may last for two-three days.

In case of allergic reactions, it may lead to vomiting, dizziness, or nausea, and the swelling lasts for a week.

Even the large local reactions subside after a week, but in case of extreme discomfort, it is advisable to consult a doctor.

Most doctors suggest taking antihistamine medication, usually Benadryl, to avoid discomfort.

Anaphylaxis

If you have a severe allergic reaction to a wasp bite, you might go into a state of shock because of wasp venom. This will cause anaphylaxis. The main symptoms of this allergic reaction include

Swelling on the face, lips, throat, etc
Lightheadedness or dizziness
Stomach cramps
Diarrhea
A sudden drop in blood pressure
Hives or itching in body areas where you aren’t even stung
Vomiting
Nausea
Loss of consciousness

The stung person doesn’t need to exhibit all of the above symptoms; most people will only show a few of the signs.

So, if you or someone you know shows the above symptoms after a wasp bite, seek medical emergency immediately.

If you already know about your condition, it is advisable to always carry wasp sting or bee sting kits with you.

These kits contain epinephrine injections that help control or stabilize blood pressure, heart rate, and breathing.

What To Do if You Get a Sting?

You may need immediate medical care if you are severely allergic to wasps or insect bites. We have discussed all the wasp bite dos in this section.

Normal Reactions

Most wasp bites heal naturally within a few hours, even if you don’t do anything.

If you want to get rid of the swelling or pain quickly and avoid potential reactions, here’s what you can do.

Wash the affected area with water and soap
Remove as much venom as possible
Apply an ice pack to the area to remove swelling and pain
Use a soft and dry towel to clean the wound
Use a bandage to cover it

In case of itching or irritation, apply hydrocortisone cream or calamine lotion. Use baking soda or colloidal oatmeal during baths.

You can also take pain relievers (ibuprofen) and Antihistamine drugs (diphenhydramine and chlorpheniramine) to quickly eliminate swelling, pain, and other symptoms.

If the symptoms don’t go away after 3-4 days of the sting, consider getting a tetanus shot.

Cuckoo Wasp Sting - What To Do? Helpful Tips

Vinegar

Soak a cotton ball in apple cider or white vinegar and press it on the stung area for several minutes. Vinegar’s acidity neutralizes the sting’s alkalinity and lessens pain and inflammation.

Severe Reactions

Do you know that up to three percent of adults and 0.8 percent of children exhibit severe reactions after a wasp bite?

If someone loses consciousness or goes into shock after a wasp or bee bite, they require immediate medical attention.

Some medical treatments for severe reactions to a wasp bite would include:

Epinephrine to stabilize blood pressure and heart rate
In case the person is not breathing, cardiopulmonary resuscitation or CPR is needed
Steroids, oxygen, and other medication to improve respiration

If you already know about your severe reaction to a wasp bite, it is best to avoid the areas where you can find these insects.

Additionally, you should carry a bee or wasp kit with you at all times.

If you see someone struggling due to a wasp bite, it is best to call 911 and stay with them until medical help comes.

Try giving them CPR in case they are unconscious and not breathing. If they have a bee kit, immediately inject them with it and wait for their immune system to calm down.

Cuckoo Wasp Defense Mechanisms

Cuckoo wasps live a rather perilous life, as we mentioned earlier. After all, invading the nests of other wasps to plant your own larvae is fraught with risk.

The biggest challenge in the life of a female cuckoo wasp is to insert her eggs inside the home of potential hosts without getting seen.

These hosts are usually other ground-nesting wasps who are capable of killing the mother cuckoo wasp with their deadly stingers.

Thus, cuckoo wasps use their bodies as armor to protect themselves from a potential attack. It curls its antenna and legs and lets its hard exoskeleton protect its body.

The defense is so effective that even the strongest of jaws or stingers cannot penetrate it, and the host has no choice but to pick up the infiltrator and throw her outside their nest.

The cuckoo wasp will then get up, dust herself off, fly back to her nest, and await another suitable time to attack.

Frequently Asked Questions

Is cuckoo wasp harmful?

Cuckoo wasps are harmless to humans but may sometimes leave painful stings. Even though their stingers have evolved into ovipositors, some of the larger species can still leave a bite.
The sting may last for a few hours unless the person is allergic to insect bites, in which case, medical help is needed.

Do cuckoo wasps have a stinger?

Female cuckoo wasps have an ovipositor to insert eggs in the host larva’s nest. They don’t have a stinger anymore.
When the wasp larvae come out of their eggs, they eat up the host larvae along with their food supply or wait for the host to eat the food and then consume them.

Are cuckoo wasps rare?

Cuckoo wasps are not rare. There are more than 3,000 species of these wasps worldwide, and more than 200 of them can be found in America and Canada alone.
However, some species of cuckoo wasps, such as Chrysidea falsa, are rare.

Are cuckoo bees poisonous?

Cuckoo bees are not poisonous to humans, but some may leave a painful sting.
Unless you are allergic to bee bites, a cuckoo bee’s sting is non-threatening and heals within a few hours. Cuckoo bee larva, however, ends up killing the larvae of its hosts.

Wrap Up

We hope this article helped you learn all about what to do when a cuckoo wasp stings you. These metallic-colored wasps are as deadly as they are beautiful, but only to their hosts.

While some cuckoo wasps might be able to sting, the pain would usually subside in a matter of a few hours. If you are allergic to wasp stings, please make sure to carry a wasp sting kit with you at all times. Thank you for reading.

Reader Emails

The shimmering, metallic appearance of this beguilingly beautiful wasp has caused many of our readers to inquire with us what manner of creatures they are.

Go through some of the letters and pictures of these beautiful creatures to understand why they are such an enigma.

Letter 1 – Cuckoo Wasp

Subject: Beautiful bee or a blue tail fly?
Location: Auburn, NJ
August 23, 2012 9:25 am
This regal creature somehow managed to find it’s way into my kitchen, where I discovered it hanging on a coffee mug the other morning. I got the camera and managed one clear focused shot before I gave her a lift outside. In sunlight the tail end appeared almost a translucent green, which I’m sorry I can’t show.
I’ve been scanning here and at bug guide, but can’t even determine if I’m looking at a bee or a wasp or a fly? The antennae and eye shape suggest one thing, the body size another. Any clue you could offer? I don’t recall ever seeing another like it.
Thanks!
Signature: Creek Keeper

Dear Creek Keeper,
This jewel-like creature is a Cuckoo Wasp in the family Chrysididae. The females lay eggs in the nests of other hosts in the order Hymenoptera to which they also belong. We suspect that each species of Cuckoo Wasp is very specific as to its host, though we are not sure if it is limited to species, genus or family. We also have problems differentiating one Cuckoo Wasp from another at the species level, though they are quite distinctive as a family. According to BugGuide: “Most species are external parasites of wasp and bee larvae; one subfamily (Cleptinae, one genus, Cleptes) attacks sawfly larvae, another subfamily (Amiseginae) the eggs of walkingsticks.” BugGuide further clarifies: “Some species are parasitoids and others cleptoparasites. Either way the host larva dies” and then further clarifies “Parasitoids feed on the larva of the host and cleptoparasites ‘steal’ the host’s food. The food-stealing behavior of cleptoparasite species resembles that of the cuckoo bird and gave rise to the cuckoo wasp’s name. Hosts of parasitoid species include bees, sphecid wasps, potter wasps, sawflies, silk moths, and the eggs of stick insects. Cleptoparasitic species feed on provisions of sphecid wasp nests, which may include dead spiders, true bugs, aphids, or thrips.”

We have found 8 of these so far living in our bedroom. So far only 2 have been alive and the rest have been dead. Being allergic to bee’s and not knowing what these are the two living ones met their maker as well. They are just about impossible to squish it seems and crunch over and over. During this I noticed their stinger is long as can be and was twitching like crazy in and out.
What is this thing and any idea why they are invading our bedroom, or more specific most of them we found are right near out window that has been closed up and what we thought sealed.
If needed I did keep the body of one of the victim and can take some more pictures.

Dear Tracy,
This is a Cuckoo Wasp in the family Chrysididae. According to BugGuide: “Some species are parasitoids and others cleptoparasites. Either way the host larva dies.” BugGuide elaborates on those term: “Parasitoids feed on the larva of the host and cleptoparasites ‘steal’ the host’s food. The food-stealing behavior of cleptoparasite species resembles that of the cuckoo bird and gave rise to the cuckoo wasp’s name. Hosts of parasitoid species include bees, sphecid wasps, potter wasps, sawflies, silk moths, and the eggs of stick insects. Cleptoparasitic species feed on provisions of sphecid wasp nests, which may include dead spiders, true bugs, aphids, or thrips.” If you have sash windows, you might want to look for the remains of a nest of Leafcutter Bees which often nest in the grooves of sash windows. Perhaps the nest of the Leafcutter Bee was parasitized by a female Cuckoo Wasp and her progeny emerged. Since you are so concerned about being stung, you should take note of this information also provided by BugGuide: “The female sting has been modified into an egg-laying tube with highly reduced valvulae and poison gland. As a result, unlike most other aculeates, chrysidids cannot sting and can be easily handled.” Most insects found in the home would much rather be outdoors, and the best way to remove them is with a glass and postcard. First trap the insect in the glass and then slide the postcard underneath the glass and move outside to release.

Hello,
I found this insect on my window screen. I captured it in a bottle so I could look at it more closely without it flying off, and after a few minutes it seemed to calm down and stay seated in the cap of the bottle. Even after I took the cap off, it did not react for a minute or so, after which it began to clean its antennae and buzz its wings a few times (without flying off). It looks like some sort of Halictid, but I could be mistaken. What do you think? Thanks!

Dear WeirdKitty,
This is a Cuckoo Wasp in the family Chrysididae, and the common name arises, according to BugGuide, because of: “the fact that these wasps lay eggs in the nests of unsuspecting hosts.” Cuckoo Wasps are harmless to humans as they cannot sting.

Oh thank you very much!!
That’s pretty interesting, I will definitly be doing more research. Thank you!

I saw this bee (?) in my yard here in northeast FL. It was a striking metallic blue, with some green especially on the underside of the abdomen. Size was about 1 1/2 to 2 cm. I thought it might be a sweat bee that was more blue than the green I usually see. But it looks like the bee might be eating something, maybe a smaller insect, which would make it something besides a sweat bee. Whatever it is, it was a beautiful blue color.

Hello there! I am an insect person who loves insects and is hoping to maybe become an entomologist one day. I have many insect pictures which I am trying to identify. I also have a collection of insects I find every now and then dead on the ground. (I don’t kill bugs for my collection, I only take them if they are dead). I do however have many I cannot identify. I have tried my 5 insect guides, google search, many bug identification guides online, and google image search but have came up empty handed. One of which I have failed to identify is this blue fly I found in the everglades. It was taken with a Sony-cyber shot camera. So I was wondering if you could help identify this insect. Thank you!

How you want your letter signed: Stephen

Dear Stephen,
You are correct that this is a Wasp, more specifically, a Cuckoo Wasp in the family Chrysididae. Though members of this family are true Wasps, they are incapable of stinging. The stinger of wasps and bees is actually a modified ovipositor that has evolved into a stinger so that female wasps can sting and paralyze prey to feed young, and it can also be used for defense purposes, especially in social insects like Honey Bees and Hornets. The ovipositor of the Cuckoo Wasps has not evolved into a stinger because the female does not need to provide food for her brood in the traditional way, nor does she defend a nest. Instead, she parasitizes the nest of another wasp to provide for her young and they either feed directly on the larvae of anther species or they feed on the food provided for the larvae of the other species, a habit known as cleptoparasitism.

Thank you so much! I know your time is valuable and busy! Is there any concern having them on the house ect? I just moved here and never seen anything like it. Extremely beautiful though.

No. Cuckoo Wasps pose no threat to you, your pets nor your home.

Thanks again Daniel! I love the service you all provide! Hope you have a wonderful day!

Letter 1 – Cuckoo Wasp or Not

Blue Wasp
Hello bugman, I took a pic of a blue wasp that was stuck in the window. Do you know what it is? I am from Vancouver Island, B.C., Canada.
Thanks
Kathy

Hi Kathy,
You have a beautiful Cuckoo Wasp, Family Chrysididae. These small wasps are usually metallic blue or green in color. They get their common name because, like the Cuckoo bird, the wasp is parasitic. According to Hogue “it lays its eggs in the nests of bees and other wasps. The larva kills the rightful occupant of the nest and develops on the provisions left in the cell by the nestbuilder.”

Update (07/29/2007) Believe you have a misidentification on a previous i.d.
Daniel: In looking for pictures of a cuckoo wasp (for which I have a nice pic I could send although you already have several), one of your identifications looks misidentified. If you look at the the pictures from Timothy and Tarik — which I believe you have identified correctly — you’ll see a generally rough looking ‘back’, and the thorax sections are not sharply separated. Also, the legs are skinny, the antennae are short, and the center of the abdomen is more bulbous than the rest. In contrast, if you look at the photo from Kathy, the back is smooth, the thorax is sharply segmented, the ‘thigh’ of the front leg is ‘muscular’ looking, the antennae are quite long, and the abdomen is fairly similar in thickness throughout its length. Not to mention that the overall color is more brilliantly blue, less green than the other photos. A check of other images on the internet shows a much closer resemblance to the blue wasp, “Aporus hirsutus”. The best example of this is found at: http://bugguide.net/node/view /31105/bgimage In particular, note the beefy upper front leg, long antennae, and other consistencies with Kathy’s image.
Oops! While I believe you still have a misidentification, another glance at the Blue Wasp photos show that this is not the correct i.d., either. I just noticed that there are two smaller photos below the larger one on the bugguide.net page, and the rear legs are cricket-like, which is clearly not the case in Kathy’s photo. I am now thinking that it at the least looks more like “Augochlorella striata” than something in the Chrysididae family. See: http://www.cedarcreek.umn.edu /insects/newslides/025066011001 apo.jpg But the smoother, more segmented back in Kathy’s photo doesn’t agree, along with the bluer color. So, I don’t think that it is any of the bugs you or I mentioned, and thus remains unidentified. Curious to hear your opinion.
Mark
