In this article, we talk about everything related to the Stage Beetle
There are only a few insects in this world that have jaws that are almost as big as their bodies. One of them is the stag beetle.
These insects have massive mandibles that look similar to the antlers of an adult stag (in proportion to their body size)
Stag beetles love to show off their big and strong mandibles to assert dominance and attract females.

Yes, they look sturdy and highly intimidating. But is there a need to be scared of these insects? The answer is no.
There are a lot of fascinating things that we don’t know about these insects, and this article will help uncover them. Time to put on your reading glasses.
What Are Stag Beetles?
Stag beetles are known for their long and strong jaws that resemble the antlers of a stag. If you compare, the male adult beetles have bigger jaws than the female beetles.
Mostly these beetles have a glossy black body with a pair of chestnut brown colored wings.
You can often spot the males indulged in brawls using their mandibles to find mates. Females, on the other hand, are mostly seen near the ground, searching for suitable spots to lay eggs.

Stag Beetle Types
Stag beetle populations are widely scattered throughout the world. You will be surprised to know that there are around 1,200 stag beetle species worldwide. Mentioned below are some details about a few of them.
Giant Stag Beetle
The giant stag beetle is considered to be one of the largest beetles that live in dead wood. These beetles show an average body size of around 2.5 inches in length.
Despite their massive size and popularity, their ideal living habitats are still unknown. The giant stag beetles highly depend on dead wood for their survival.
Also, the giant stag beetle larvae are mainly found in wet logs.
Giant Stag Beetle
Cottonwood Stag Beetle
Cottonwood stag beetles, also known as Lucanus mazama, usually prefer to stay in areas with loose soil and high temperatures.
Similar to most stag beetles, they too have shiny black bodies. They generally grow from 1.02-1.14 inches in length.
A riparian area with plenty of old cottonwood trees is a suitable environment for these insects to live and grow.

Golden Stag Beetle
Unlike most of its relatives in the stag beetle family, the golden stag beetle is not glossy black.
These beetles have shiny bodies with a touch of golden hue and measure between 0.59 to 0.98 inches in length.
The adult beetles are mostly golden green, golden yellow, and dull brown in color. Some Golden female stag beetles can also be blue and blue-green.
Such beetles are native to Australia and can be abundantly found in different regions of Tasmania, Victoria, and South-East Australia.
Golden Stag Beetle
Rainbow Stag Beetle
Rainbow stag beetles (Phalacrognathus Muelleri) are native to the forest areas of Queensland, Australia.
Similar to the golden stag beetles, they, too, have colorful bodies that resemble the flashing colors of a rainbow.
Like most stag beetles, they have two huge mandibles which differ in size according to the gender of the insect.
The males have larger jaws compared to the females. Also, if you look closely, you will notice that the females have longitudinal marks on the thorax.

Stag Beetle Vs. Rhino Beetle: How To Differentiate?
The rhino beetle is another insect that is known for its giant jaws. Similar to stag beetle weaponry, they use them to fight to win territories and mating rights.
Both these insects might look alike at first glance, but if you look closely, you will notice that the Rhino beetles have mandibles that jut forward from their head like a Rhino.
While the stag beetles horns are placed horizontally.
The Rhino beetles are also bigger and a little heavier than the stag beetles.
What Does A Stag Beetle Eat?
Adult stag beetles do not consume solid food; the females drink sweet juices obtained from decomposing fruits, tree saps, vegetables, plants, etc.
Males rely on the fat reserves built during the larval stage.
During this stage, the larvae actively consume dead and decaying matter like wood to store fats in the body, so they can survive well as adults.
Apart from being near some log piles, they also like to be around traditional orchards, parks, and gardens (with dead wood around).
Also, they prefer to be in warmer regions where the larvae can grow rather than in shaded canopies of dense forests.
Life Cycle of A Stag Beetle
The female stag beetles can lay up to 24 eggs at once. It all starts when the males get attracted by the female pheromones, and often they indulge in fights to win mating rights.
The female searches for an underground spot near rotting wood to lay the eggs. These eggs are tiny and take around 30 days to hatch.
When the larvae emerge, they are white in color, but after a while, it starts developing a unique bright orange color.
As soon s it emerges, they transfer to the nearest deadwood pile, where they feed for almost six years before emerging as adults.
The primary purpose of continuously eating is to have enough fats stored in the body so they can use them as adults to survive.
Right before moving into the final stages of being a larva, they start building a cocoon around themselves.
This is usually made of chewed wood and mud. After completely covering itself in this shell, they start pupating.
From this stage, you can start distinguishing between the males and the females. The males will slightly pierce out their mandibles from the pupa.
It takes around 60 days for the pupation period to complete. By the summer, a fully developed adult stag beetle emerges from the ground and goes on to start this cycle again.
Mating Rituals of Stage Beetles
As mentioned in the above section, the males are attracted to the female pheromones. Once they locate the female, try to win her over by putting on a display of their antlers.
They open their jaws wide and walk slowly to show off their features and to impress the female.
If there is more than one male interested in the same female, the score is settled through a fight.
Here both parties wrestle with each other using the mandibles.
Whoever can turn the opponent on its back wins the fight and earns the mating right. The loser has to depart and try his luck somewhere else.
The brawls are not too dangerous, with injuries being unlikely. Also, the males often prefer to mate with multiple females.
How Long Do Stag Beetles Live?
It takes around 30 days for the larva to emerge from eggs. From there, they take almost six years to come out as adult stag beetles. The adults can only live for a few weeks and spend most of their time mating and reproducing.
Do Stag Beetles Bite?
Stag beetles are not aggressive and dangerous, but you can’t ignore the fact that these insects have huge and strong mandibles that can be used for biting.
Therefore you must not mishandle these insects as they will think that you are trying to attack them and bite back in defense.
Since they have strong chewing muscles, the bites can be quite painful.
Are They Poisonous/Venomous?
Stag beetles have a sturdy and intimidating appearance, but in reality, they are not harmful to humans.
Yes, they can deliver painful bites, but these bites are not venomous and won’t cause any fatal injury or illness. They will not attack if you don’t disturb them.
Are They Harmful to Humans and Pets?
Stag beetles are not harmful to humans if they are not constantly threatened and disturbed.
If you approach these insects recklessly, they will use their strong jaws to bite, which is very painful.
Can They Come Inside Homes?
Stag beetles larvae usually stay underground near dead and decaying wood.
There is very little chance of them entering your homes as they prefer to be around the food source that is dead and decaying matter.
What Are Stag Beetles Attracted To?
Stag beetles are attracted to warm regions with loose soil, where they can lay eggs.
They also like to be around places that have plenty of sources to get dead and decaying matter like rotting wood.
Sometimes adults are also attracted to lights at night.
How To Get Rid of Stag Beetles?
These beetles might sound fascinating but having them around your home and garden is a little too much.
To get rid of these insects, you must ensure that you remove all the foliage in your garden every day.
Make sure that you remove all dead and rotting pieces of wood from the garden, as they are prime locations for the stag beetles to live.
If you come across a few near your house, catch them using safety gloves, and drop them in soapy water to exterminate them.
Interesting Facts About Stag Beetles
Apart from the things mentioned in the sections above, there are a few more notable things about stag beetles that are highly interesting. Here are a few of them:
Stag beetles are also found in the UK, and the European stag beetle (Lucanus cervus) is considered one of the largest beetles in the entire country. They can grow up to 2.95 inches in length. This is almost equal to the size of an adult human thumb.
The size and strength of an adult stag beetle are determined by the amount of dead and rotting wood these insects consume as larvae. Therefore, the females need to lay eggs near spots with an abundance of food.
The fights between the males to earn mating rights highly depend on the size of the mandibles. Whoever has larger jaws will most probably win the battle. If both opponents are evenly matched in terms of size, it can take several minutes or even hours for a brawl to end.
In the UK, you will find these beetles in southeast England. They are common along the regions of Severn valley and the southwest coast. You will also spot them near the southern and central regions of Europe.
Frequently Asked Questions
Is Stag Beetle rare?
There are around 1,200 species of stag beetles scattered around the globe, so they are not rare in this sense. These fascinating creatures are found in different regions of Australia, the UK, the US, and more. They prefer to be around loose soil, and warm temperatures to they can easily lay eggs underground.
How do you identify a Stag Beetle?
Stag beetles can be easily identified by the two long mandibles that look like the antlers of a stag. Mostly they have black-colored bodies. In some cases, they can be dull brown, metallic blue, golden green, golden yellow, and even multicolored like a rainbow. The larvae have a distinct orange-colored body, and they live in decaying wooden logs
Is it safe to pick up stag beetle?
You should not pick up a stag beetle with bare hands. These insects have big mandibles and strong chewing muscles. Moreover, they can bite. The bites can be quite painful. If you want to pick them up, it is wise to use safety gloves to stay safe from the bites.
Why am I finding stag beetles in my house?
At night adult stag beetles are attracted to warm surfaces and light sources. So if you find these insects in your house, they probably were chasing the lights during night time. Also, since they are attracted to decaying wood, it is good to keep your surroundings clean to avoid them.
Wrap Up
Although stag beetles are found in large numbers worldwide, there is a lot that we don’t know about these insects.
These insects can live up to 7 years and spend most of their lives as larvae consuming dead wood. They are extremely fierce when it comes to mating.
The males often brawl to win mating rights. Despite all this, these insects are not at all harmful to humans and pets.
Reddish Brown Stag Beetle
Yes, they can deliver painful bites but only when they feel threatened. The stag beetles are not at all aggressive towards humans.
We hope the article gave you an overall idea of what these insects are. Thank you for taking the time to read the article.

We are saddened that this noble Reddish Brown Stag Beetle, Lucanus capreolus, has met an untimely end, but we are uplifted to know that you did not play a part in its demise. Our own feline occasionally catches and eats something we wish had escaped her claws. Judging by the size of the mandibles, this is a male Reddish Brown Stag Beetle.

Stag Beetle?
July 13, 2009
There were several of these bugs coming out of the ground/grass, where I had noticed holes about the size of quarters a few days prior, at dusk. Are these the giant stag beetles? I think there may be an old tree stump in the ground here.

Another Stag Beetle!
July 15, 2009
THANK YOU for choosing to make the stag beetle your “Beetle of the Month”. Why? Because my wife found one in the bathroom late last night (!), and I had to figure out what it was before either of us could go to bed. Posting an image on your home page made it quick and easy to get back to sleep knowing we didn’t have a martian invader in our home.
Based on some more research, it seems that maybe it’s unusual to find such a creature in NJ–only 12 miles from Manhattan.
Anyway, I didn’t kill the creature. But here is a picture of him trapped in a glass before I let him outside. (Well, first I checked that it wasn’t a poisonous monster.)
Thanks for your hard work on the site. It really was appreciated last night.

Reddish Brown Stag BeetleHi Russell,
Based on the number of letters we have received with images of the Reddish Brown Stag Beetle, we chose the wrong species as our Bug of the Month. The Giant Stag Beetle has much more impressive mandibles, but there doesn’t seem to be as many sightings. We are happy that you were able to identify this close relative based on the image on our homepage.

We are trying to post a few new letters before attending to things around the house that need attention since we just returned yesterday. Your letter was the first subject line that caught our eye from the June 22 submissions because we love Stag Beetles and we were happy we didn’t need to spend any time doing research towards an identification. This is, as you indicate, the Reddish Brown Stag Beetle, Lucanus capreolus, and it is a male as evidenced by his large mandibles. There is some great information on BugGuide.

Hi What’s The Bug?,
I am a huge fan of your website, and I thought you might be interested in seeing a few photos I have taken. I primarily photography fish, but I’m also very interested in bugs. Thanks to frequenting this site I knew right away that the bug in the first photograph was a stag beetle. By the time I took the photo of the fly I had purchased a macro lens, which is why there is a significan improvement in the photo quality. Enjoy, and keep up the excellent work!

Thanks for the compliment, and we can also tell you to keep up the excellent work. Your Reddish Brown Stag Beetle image is especially nice. Most of our Stag Beetle reports come in July, so you photo is a nice anticipation of what summer may bring. Can you provide us with the actual location for the Stag Beetle? Is it MN, NH or MA?
Thank you so much for the feature on the front page! The photo of the stag beetle was taken in MN near the Twin Cities.

Pair of Reddish Brown Stag BeetlesHi Mark,
We are so excited to be able to post your photos of a pair of Reddish Brown Stag Beetles, Lucanus capreolus. It is also wonderful to have such nice documentation of the sexual dimorphism. The male has the much larger mandibles, and they are allegedly used in sparring contests as males vie for the attention of a female.
Female Reddish Brown Stag Beetle
We hope you released this magnificent pair of Reddish Brown Stag Beetles back into the habitat so that they are able to perpetuate the species. The larvae of Stag Beetles are significant contributors to breaking down rotting wood so that it can be incorporated into soil as humus, thus increasing the fecundity of the soil.

Mr. and Mrs. Stag Beetle in my Kitchen Sink
Location: Chelmsford MA
July 7, 2011 1:37 am
Hi Folks,
I live in Chelmsford, MA. Thanks to your website, I was able to identify these enormous critters in my kitchen sink – I think they are male and female Reddish Brown Stag Beetles.
I have found at least two or these beetles in my kitchen sink every year at about the same time of year (early summer). Yesterday there were three of them in my sink. They must be coming up the drain, because anything that large flying in the house would drive my cats wild.
My questions are:
– Why do they come in to the sink every year?
– Is this normal stag beetle behavior?
– Should I be worried about the condition of my foundation or plumbing?
Your website convinced me that these bugs were worth saving, so I gently set them down in my yard.
Thank you so much for any insight you might be able to give!
Sincerely,
Frances Killam
Thank you for your help,
Frances Killam
Stag Beetles in the Kitchen SinkHi Frances,
This is most perplexing. We read your email just prior to closing the offices for the night, and we felt we needed to be rested and refreshed before we tackled a response. After a good night’s sleep, we still don’t have a conclusive answer for you. Stag Beetles do spend their larval stage feeding on rotting wood, so there must be a suitable habitat nearby. We found this marvelous British website Stag Beetles for Everyone that may provide you with some insight. We can’t imagine that the Stag Beetles are entering your home through the drain and we would suspect that they have flown in. Perhaps they are attracted to lights, and if a female arrived first and fell into the sink, her pheromones might attract willing male suitors. The sink is a trap for many creatures, and once inside, they are stuck. Perhaps other Stag Beetles have entered your home and those became cat food. We would also encourage our readership to provide their opinions in our comment section.

I found this stag beetle on my front porch in the morning laying on his back.
My question is-
Do you think he was dying?
Every time I tried to flip him right side up, he would flip himself onto his back and lay there slowly wiggling his legs.
I tried several times to help him out but he continues to flip onto his back.
Eventually I just moved him into the grass.

We don’t know what is causing this male Reddish Brown Stag Beetle to keep flopping onto his back, but it doesn’t sound like normal behavior. I would seem that something is amiss.

Reddish Brown Stag BeetleDear frightened bug lady,
This is a female Reddish Brown Stag Beetle, Lucanus capreolus, and she is not dangerous to people. Both females and males, which have considerably larger mandibles, might nip if carelessly handled. According to BugGuide: “Larvae feed in rotting logs. They are not harmful to vegetation.” Perhaps there was a rotting log or tree near where your wife was weeding.
thank you for the quick response, I’m sure she will be more at ease and I’ll look in the ground cover for some rotted wood.

Reddish Brown Stag BeetleDear Rose,
This is a male Reddish Brown Stag Beetle, Lucanus capreolus, and he is a magnificent creature. According to BugGuide, adults feed on: “Tree sap. Adults in captivity for study will readily drink diluted maple syrup or sugar water. Larvae feed in rotting logs. They are not harmful to vegetation.” Stag Beetles can fly and they are attracted to lights, so this individual may have emerged some distance from your home. Stag Beetles are not destructive. They need rotting wood like stumps and logs to survive since the larvae take several years to mature.

Signature: Mel
Male Reddish Brown Stag BeetleDear Mel,
In our opinion, you should not move and concede the territory because of your encounter with this male Reddish Brown Stag Beetle, Lucanus capreolus. Females have smaller mandibles. Stag Beetles will use their mandibles to defend themselves, but as you observed, Stag Beetles are not aggressive, nor are they dangerous. They are attracted to lights, which probably explains its presence on the screen door.

Signature: Robyn
Brown Stag BeetleDear Robyn,
The quality of your image, including the focus, is not ideal, but we believe this is some species of Stag Beetle in the family Lucanidae. Your individual looks very much like an Australian species,Rhyssonotus nebulosus, and we wonder if thy might be closely related.We soon learned that this Australian Stag Beetle has become established in New Zealand. This New Zealand Entomologist pdf indicates that: “Ryssonotus nebulosus (Kirby) is a large (20-30mm) Australian stag beetle. According to Moore & Cassis (1992: 16), it has the rather uninspiring common name of ‘Brown Stag Beetle’. It is rather badly named, for it is a mottled khaki colour. … Gourlay (1954) first reported the presence of R. nebulosus in New Zealand. It is well known to be established in the Gisborne region, but its presence in the Auckland region has never before been reported. It has been there since at least 1967. It is amazing how such a large and spectacular beetle could go almost unnoticed in urban Auckland for so long.”

This is the third image of a Reddish-Brown Stag Beetle we have posted to our site in the past two day. The first we posted yesterday, though it was submitted from Delaware in June while we were on holiday and not responding to identification requests.The second arrived from New Jersey today and was posted today. A third was a very blurry image from Wisconsin that was not posted. This is the season for emergence of these magnificent beetles in Eastern North America. They are attracted to lights.

Pretty sure this is a stag beetle of some sort. Saw him last night and left him alone.

I went to investigate and it was this lumbering bugger making all the noise. I’m forty-three and have never had so much interest in bugs and birds. This one is a treat. He looks so menacing but seemed quite peaceful. Seemingly a large one based on what I found was the average size. Removed him from our fenced yard so the dogs don’t bother him. To live another day.

Hi Bugman —
The “Lucanus capreolus, Reddish-brown Stag Beetle” in the attached photo would like to thank you for saving its life! Normally, I’m a “Smash First, Ask Questions Later” kind of person when it comes to bugs, and had it not been for a recent visit to your website, where I happened upon a picture of the Elephant Stag Beetle, “Smash First” would definitely have been my reaction upon catching sight of this monstrous *beast* hanging out near the garage door on Sunday. (It was five inches long! I swear! Well… in my head, anyway. In reality, it was probably about 1.5 inches long.) Anyway, having learned from WTB that these are fairly harmless to people, I let him be. Last I saw, he was headed back to sit amongst the geraniums. (Where, unbeknownst to me until I checked the photos later that evening, he had been hiding out while I was taking some other flower pictures. (Mental note to self: Always wear your Mud Gloves when poking around in the flowers.)) Also attached are some pictures of a Firefly (Lampyridae), Genus Photinus, crawling around on the aforementioned geraniums. I couldn’t find any of this particular genus on your website already, and thought you might like some. Thanks again for WTB!

Male Stag BeetleHi Gordon,
This magnificent beetle is a Male Stag Beetle, Lucanus cervus. According to the Natural England website: “This species is now rare and declining in Europe.” The website also provides this tip: “In a recent survey of the species, 70% of sightings came from domestic gardens. You can provide a habitat for stag beetles and other dead wood insects by making a pile of logs, ideally with bark on them, placed upright in partial shade and sunk partially into the ground, with plants growing over them to retain humidity they need.” The UK Safari website has nice information and photos on the life cycle of the Stag Beetle including these special features: “This is the largest beetle found in Britain, and now sadly, quite rare. The most noticeable feature of the male are the large antler-like jaws, which give the beetle its name. They are used during the mating season to fight with other males over territory. Each male tries to grab his opponent between his jaws, and then throw him. The fully grown male stag beetles can normally be seen flying at dusk between May and August. The warmer temperatures at this time of year encourage them to look for a mate. They will drink tree sap, but do not eat, and will not grow at all. After mating the stag beetle dies.” You may also be interested in this article on attracting Stag Beetles with ginger from the BBC website.

You are correct. This is a Reddish Brown Stag Beetle, Lucanus capreolus. It is a male and it is not harmful to people or pets, but you should be forewarned that he is capable of pinching and it is conceivable that a pinch might draw blood, but rest assured that the Stag Beetle has no toxins nor poisons known to man.

Stag Beetle CarnageDear Stephen,
We are very disturbed by your image of a very dead male Stag Beetle, Lucanus cervus, because indications are that it was alive when you found it. Stag Beetles are perfectly harmless as they have neither venom nor poison, and the large mandibles of the males are not used for biting people, but rather to fight among themselves when competing for a mate. This is considered an endangered species throughout much of Europe. According to The Wildlife Trusts: “Protected in the UK under the Wildlife and Countryside Act, 1981. Classified as a Priority Species in the UK Biodiversity Action Plan.” The Wildlife Trusts also states: “The Stag Beetle is the UK’s largest beetle and is found in south-east England, particularly in south and west London. It prefers oak woodlands, but can be found in gardens, hedgerows and parks. The larvae depend on old trees and rotting wood to live in and feed on, and can take up to six years to develop before they pupate and turn into adults. The adults have a much shorter lifespan: they emerge in May with the sole purpose of mating, and die in August once the eggs have been laid in a suitable piece of decaying wood. Look for the adults on balmy summer evenings, when the males fly in search of mates. Once the male has found a mate, he displays his famously massive, antler-like jaws to her, and uses them to fight off rival males, in a similar fashion to deer.” According to People’s Trust for Endangered Species: “Spectacular stag beetles are one of our largest beetles. Sadly their numbers are declining across Europe and they are now extinct in some countries. In the southern parts of the UK they are doing much better but they still need our help.” According to UK Safari: “Stag Beetles are the largest beetles found in the U.K. and they’re now quite rare. The decline of our Stag Beetles is mainly as a result of habitat loss. Some are killed by cars on roads, and since they spend such a long time in the larval stage they are also vulnerable to predation.” According to BBC: “One of the UK’s most iconic insects is under threat and becoming increasingly rare to find, and that’s a real shame.” We hope the next time you encounter an unknown creature, you resist the urge to kill it because there are really very few animals in London that pose any threat to humans, and that you make an attempt to identify it before taking such an irreversible action. We hope you teach your children to appreciate the wonders of the natural world and not to fear them. Our mission from our inception has been to provide information to the web browsing public so that they have a better appreciation of the lower beasts. Alas, we have no choice but to tag this posting as Unnecessary Carnage.

The only stories I’ve ever heard about bugs coming out of drains, is when a tap that isn’t used for a long time is finally turned on, whatever was living in it before (usually a spider) is flushed out by the water. I recently had a situation similar to this one, except it was with a giant slug in the bathtub. I know it didn’t come out of the drain, and I’m pretty sure I would have seen it slowly making it’s way to the bathroom, but I didn’t. Bugs can be very sneaky and can crawl into homes through very small gaps that we wouldn’t normally notice. There’s also a theory that all living things are attracted to the energy of running water. I’m not sure if it’s true or not, but it sure would help explain why everyone’s always finding critters in the sink or tub!
I’ve seen the “back-flipping” a few times before, and most of the time it was because the bug was either sick or hurt. I’ve also seen it happen after a bug was suddenly moved from once space to another, but after a few minutes, they permanently flipped over on their legs and went on their merry way.
Just this day here in central Indiana I saw a stag beetle and my friend said he had also seen them this week. I had to look on this site to identify the species (tonight), are these seasonal? Is there a hatch in progress?
Stag Beetle sightings peak in July and this helps to ensure that mature individuals capable of mating will also be coeval, though stragglers may be early and late.
I saw a similar one on my driveway that was almost all black. Oddly, I saw another one at an orthodontist’s office doing the same behavior. Can anybody identify him? It is near Toledo, Ohio (northern Ohio, less than 60 minutes from Detroit.)

I enjoyed your response, but the pedant in me objected to the line “Did you attempt mouth-to-mouth resuscitation?” After all, insects don’t breath through their mouths. I understand that mouth-to-thorax resuscitation might seem a tad creepy, but for bugs the breath of life is sustained by the miracle of spiracle.
Hey.. I was out in my yard today and came across this bug.. he was on his back and struggling, so I helped him flip over and then moved him to a safer location (away from foot and paw traffic and nosy dogs). He seemed to be a bit wobbly..
Then, a few hours later, I found him again, on his back. This time, I flipped him over and he held his head up and his pincers open.. but I got him moved to another ‘safe’ location.
I got some pictures and thought I’d share. I wasn’t sure what it was until I found your site in a google search. Thanks!

Found a stag beetle on my shoulder one night after sitting on the front porch. It was a male I am assuming, it had two pinchers. I thought it may have pinched my shoulder or it could have been the legs trying to hold on. this stag beetle was found in Piedmont, Alabama

Strangely, I’ve only seen two in my life. The one pictured above, and a larger Black Stag Beetle around 20 years ago in a similar location.
Beautiful, aren’t they?
The only stories I’ve ever heard about bugs coming out of drains, is when a tap that isn’t used for a long time is finally turned on, whatever was living in it before (usually a spider) is flushed out by the water. I recently had a situation similar to this one, except it was with a giant slug in the bathtub. I know it didn’t come out of the drain, and I’m pretty sure I would have seen it slowly making it’s way to the bathroom, but I didn’t. Bugs can be very sneaky and can crawl into homes through very small gaps that we wouldn’t normally notice. There’s also a theory that all living things are attracted to the energy of running water. I’m not sure if it’s true or not, but it sure would help explain why everyone’s always finding critters in the sink or tub!
That is a very nice explanation Jessi. Thanks for commenting on this interesting occurrence.
Update-
An hour later I checked on him and he was indeed dead. He is sitting in my herb garden for the kids to take a look at.
Thank you.
I’ve seen the “back-flipping” a few times before, and most of the time it was because the bug was either sick or hurt. I’ve also seen it happen after a bug was suddenly moved from once space to another, but after a few minutes, they permanently flipped over on their legs and went on their merry way.
Just this day here in central Indiana I saw a stag beetle and my friend said he had also seen them this week. I had to look on this site to identify the species (tonight), are these seasonal? Is there a hatch in progress?
Stag Beetle sightings peak in July and this helps to ensure that mature individuals capable of mating will also be coeval, though stragglers may be early and late.
I saw a similar one on my driveway that was almost all black. Oddly, I saw another one at an orthodontist’s office doing the same behavior. Can anybody identify him? It is near Toledo, Ohio (northern Ohio, less than 60 minutes from Detroit.)

Here is a link to our identification form. Please attach a photo and submit.
How to ride of them? Thay are in old tree stumps & near my flowers. Please help! Thay have babies to.
three of these just hatched in from a stump in my garden today (Southampton, UK). pretty cool!
Congratulations. We understand their numbers are diminishing in the UK.
Just a quick note to tell you your new posts have not been showing up on the front page of the blog since July 11th! That’s 25 1/2 pages of of blog going unread!
Very curious. It seems fine on our end, so we are copying our webmaster to get his opinion. This is our most recent posting. If they are not showing, how were you able to comment?
I enjoyed your response, but the pedant in me objected to the line “Did you attempt mouth-to-mouth resuscitation?” After all, insects don’t breath through their mouths. I understand that mouth-to-thorax resuscitation might seem a tad creepy, but for bugs the breath of life is sustained by the miracle of spiracle.
You are absolutely correct, but our response was prompted by the querent’s subject line. Thanks for pointing out the scientific absurdity in our joke.
Can this bug fly. We found in our pool. Is it poison?
No poisonous. We believe Stag Beetles can fly.
Hey.. I was out in my yard today and came across this bug.. he was on his back and struggling, so I helped him flip over and then moved him to a safer location (away from foot and paw traffic and nosy dogs). He seemed to be a bit wobbly..
Then, a few hours later, I found him again, on his back. This time, I flipped him over and he held his head up and his pincers open.. but I got him moved to another ‘safe’ location.
I got some pictures and thought I’d share. I wasn’t sure what it was until I found your site in a google search. Thanks!

Found a stag beetle on my shoulder one night after sitting on the front porch. It was a male I am assuming, it had two pinchers. I thought it may have pinched my shoulder or it could have been the legs trying to hold on. this stag beetle was found in Piedmont, Alabama
I was just driving home when I felt something on my leg I went down to swipe it off n it bit me it hurt and I started bleeding, I didn’t know were it went but next thing I knew it was on my arm and I didn’t even see it fly
I pulled one of these bad boys out of my pool skimmer. It was seemingly dead. Now it is back to life! Its huge.
We found the Reddish Brown Stag Beetle in our backyard rock garden in Chatham, New Jersey. We got a really good look at him/it but didn’t have a cell phone or camera outside with us. It is definitely the same as your picture(s) and had definite curved horns.
just found one 2 1/2 inches long looks right menacing will have to release him back into nature.
I found one in my room this morning ( have no clue HOw he got in here) and he keeps flipping over, and like I would put him outside but…. I kinda feel like he’s gonna be dead in 30 secs if I do that…?

My son’s friend was bitten by a stag beetle tonight.
When my son tried to remove it from his arm, it hang on quite a bit. Luckily it let go and my son was able to catch it alive and throw it back outside.
