Australian Stag Beetles

Pair of Beetles in Northwestern Sydney, Australia
Sat, Dec 20, 2008 at 4:44 PM
Hey guys!
This is my second time writing in, only not for a few years. I was ratting around in a rotten wood pile in my backyard in Galston (which is northwestern outskirts of Sydney), and found this glorious pair of beetles. I’m assuming by the difference in mandible size that I have a female and male, but for the life of me I cannot find them anywhere on any site. Have you got any clues for me?
Ps: In my last letter, I mentioned getting a bug themed sleeve- well it’s 90% done and I even got the botany bay weevil included in there :)

Unknown Beetle

Stag Beetle

Hi Ash,
We need to do some research on the identity of your interesting beetles, but we need to rush out of the house right now. We will post the images and research later, but we are also hoping one of our readers can provide a proper identification as well.

Update December 24, 2008
Hi, Daniel:
The “unknown Australian beetles” are stag beetles, family Lucanidae. I’ll see if I can’t find out more…..Do I rock or what?! LOL! I found the species of those “unidentified Australian beetles.” They are stag beetles, family Lucanidae, specifically Rhyssonotus nebulosus. Great name for a really cool insect.
Take care, best to Lisa, too.

That’s fantastic! I feel really proud of myself as a budding entomologist that I was able to guess (by body structure) that they were some sort of stag beetle. Thanks heaps.

Reddish Brown Stag Beetle

Hey bugman,
I live in Seymour, Tennessee, which is in the Knoxville area, and today I found this beautiful stag beetle under a garbage bag full of leaves that is currently sitting on our back patio. I know you probably get a lot of stag beetle images but these turned out so nice I had to share them with you. Enjoy! I cant thank you enough for the hours of entertainment I have gotten from your site.

Hi Michael,
We are thrilled to post your exquisite image of a Reddish Brown Stag Beetle, Lucanus capreolus.

Giant Stag Beetle

Dear Bugman,
We are enclosing photos of what we think is a giant stag beetle. We found him this evening in our yard in Lexington, NC being knocked around by our neighbors cat. When we tried to get him into a container to bring him in for a photo, he reared his head up and used his pinchers to grab our stick. Will you please let us know if we are right. thank you,
Daragh Conrad

Hi Daragh,
This is indeed a Giant Stag Beetle, Lucanus elaphus, and it looks like he didn’t fare so well in his encounter with the cat.

Stag Beetle

Hi,
I’ve pored over your 19 pages of beetles, (with many pauses for distraction by fascinating photos & letters) But haven’t been able to identify this big shiny smooth black beetle. The closest match seemed to be a Bess Beetle, but the proportions don’t seem right. and ours don’t have the lines running along the back. The photo was taken at night, with a flash. Sorry it lacks detail. They’re very glossy black, we see them here at our house in Minneapolis on June / July nights when they visit our front door screen (Under a porch light) some times 2 or 3 of them at a time. They are slow moving, they rise up into an aggressive posture when disturbed. One time I found one with its feet up floating in a bowl of water, not moving. I brought it inside and left it in a tray on the counter and after 3-4-days of "Death" it came out of whatever suspended state it was in and began to walk around. We decided we like them better outside than in! Thanks for your help!
Dave Ahl

Hi Dave,
We admire anyone who will pour over all nineteen of our beetle pages in an effort to identify a mysterious visitor befor writing to us. This is a female Ox beetle in the tribe Oryctini. We are not certain if it is in the genus Xyloryctes or the genus Strategus. Perhaps Eric Eaton can provide the answser for us.

Daniel:
The image is of a stag beetle, Lucanus placidus. In your defense, that is one awkward angle to make any kind of identification from! The entire head of the animal is virtually undefined. It took me a bit to see that the antennae were ‘wrong’ for a scarab….More images and information can be found at Bugguide (or I would not have been able to reach a proper conclusion myself!). One other clue was the behavior described: “rearing up” is classic for stag beetles, almost unheard of in scarabs.

Reddish Brown Stag Beetle

Flying in our backyard in Portland Maine
Hi,
This large beetle, about 2 inches in length was flying around our screened in porch tonight (july 1, 2008). I’ve never seen anything like it and was hoping you would identify it for us. We live in Portland, Maine, in the city but on a very green and tree-lined street. Thanks in advance.

This beauty is a Reddish Brown Stag Beetle, Lucanus capreolus.

Giant Stag Beetle

I found this bug in my Marigolds on 6/30/08 in northern central Tennessee. I also believe I seen a very tiny bug just like this one within a foot or so at the same time. Although, it was virtually clear in color, I think it was a baby. Is this a Stag Beetle or something else ?
Phillip

Hi Phillip,
What a beautiful male Giant Stag Beetle, Lucanus elaphus. Immature Stag Beetles are grubs and look nothing like the adults.

Stag Beetle

need help!
I live in Minneapolis, Minnesota..and the past two weeks we have been infested with these bug in the back yard. They have not made it inside the house yet, thank goodness! It pinched my husband the other night while he was outside and it latched on to my Westie’s nose, and sent her barking and crying! >Can you help me? We have asked all of our neighbors and no one has ever seen anything like this in our area. What is this thing? And how do I get rid of it? Thanks,
Heather

Hi Heather,
This is a Stag Beetle. We are not certain what species, and we will enlist the assistance of Eric Eaton with a more exact identification. You must have a plentiful larval food source in your immediate vicinity. The grubs eat rotting wood, so perhaps a dead rotting tree or a neglected firewood pile is the source of the Stag Beetle population explosion.

Update: (06/29/2008) About the Stag beetle
Dear Heather, I know it’s not great to get pinched, and I am sorry that happened to your husband and your dog, but please don’t try to eliminate your stag beetles, they are a vital part of the forest ecosystem. Probably where your house is now used to be forest not too long ago, or perhaps you are near the edge of forest still. It sounds as if this year there is a surge in the population of stag beetles, and right now the adults are all hatching out, but very soon they will all disperse to find other dead wood, and you won’t be bothered by them any more. Stag Beetles are impressive, and to me they are some of the aristocrats of the beetle world. Best to you,
Susan

Dear Daniel:
The stag beetle is either a female or “minor” male of the “pinching beetle,” Lucanus capreolus. Am I going to hell because I laughed at the poor doggie? I can’t imagine an “infestation” of stag beetles, but simply turning off the outdoor lighting would help. They are attracted to lights at night. In the absence of that attraction they will probably fly elsewhere to look for mates.
Eric Eaton

Thank you so much for your response and your assistance. Now that we know what they are, and that they are not a threat or anything, we will let them be and hopefully they will move on soon on their own. No one will be going to hell for laughing at the fact that my poor puppy (only 12 weeks old) got “pinched.” It was quite the sight and we laughed too. :) Thanks again!
Heather

Correction: (07/04/2008) Forwarded by Eric Eaton
Hi Eric!
I had a look at What’s That Bug , and would like to suggest that this entry Stag Beetle is probably a Lucanus placidus. Once I had an interesting correspondence regarding this species from Minnesota as well, and posted the lot in the bugguide. Interesting to know that it is you running this site, I used to visit when I had a lot a stag beetle emails, this before the emergence of the bugguide! All the best,
Maria

Stag Beetle

Dorcus Brevis or Dorcus parallelus???
Hey bugman,
I found this small beetle (about half an inch long or so) under a rotting log at the edge of the woods behind our house here in Seymour, Tennessee. I know its a stag beetle in the genus Dorcus, but would love to know which of the two Dorcus species found in the US it is. anyway i hope you enjoy the photo. any help would be appreciated. Thanks again for one of my favorite websites.
Michael D.

Hi Michael,
We would love to be able to provide you with an exact species, but that level of taxonomy is way beyone our capabilities. If Eric Eaton and BugGuide can’t do it, we are not going to be much help. We noticed you have already posted your image to BugGuide, and we hope that you will get some results. BugGuide is the best source for accurate and obscure identifications of North American insects. BugGuide is the serious brother of insect identification websites, and we are just the smart mouthed, brash and sassy sibling. We are rotating your image 90 degrees clockwise since it fits our site better that way.

Giant Stag Beetle

“YOU’VE GOT TO SEE THIS!” – Stag Beetle in Illinois
Hello and congratulations on such an informative website. We live in a wooded area with a small pond in South-Central Illinois, a suburb of St. Louis, MO. In June 2007, my husband encountered this enormous bug on a decorative wagon wheel while cutting grass. He ran into the house to get me and the kids saying, “YOU’VE GOT TO SEE THIS!” My husband grew up on a dairy farm and has seen lots of bugs in his day but never came across anything like this. At first we thought it was an escapee from the insect house at the zoo. After searching the internet, we came across your wonderful site and quickly identified it as a Stag Beetle. We’ve enjoyed watching bugs for a while now but it is one of the biggest we’ve ever seen – it measured 3 inches long. We were afraid to get too close so as not to get surprised. However, we did get close enough to see the dew on its back! Do they fly? Are they common? Any information on this elegant insect would be appreciated.

Hi Denise and John,
Your Giant Stag Beetle, Lucanus elaphus, is a beautiful specimen. They do fly. According to BugGuide, they are more common in the southeast, and “There is some conservation concern about this species. The related Lucanus cervus , of Europe, is threatened.”

Brownish Red Stag Beetle

Beetle?
We found this sucker on our screen near the spotlight at night. It’s about an inch or so big. Please help us figure out exactly what it is. Thanks!

Hi Scott
This ia a male Brownish Red Stag Beetle, Lucanus capreolus. They are attracted to lights.

Lesser Stag Beetle from England

Unknown black beetle
Dear Bugman,
Firstly, thanks for your excellent site! It helped me identify a cockchafer that flew into my lounge a few months ago. Now I’m hoping you can help me with a little black beetle I recently found sitting in the middle of my kitchen. I’ve looked at all the pictures on your site and can’t find anything that quite matches this guy. I thought he might be either a Bess beetle or a bark-gnawing beetle, but he doesn’t seem to quite match closely enough. Maybe some kind of scarab? Can you help please? (By the way, I live in London, England.) Many thanks,
Claire

Hi Claire,
We quickly identified your Lesser Stag Beetle, Dorcus parallelopipedus, on an English Nature website. Since they fly and are attracted to lights, that would probably explain its presence in your kitchen.

Hi Stacey,
We thought for a moment you were trying to teach this spectacular Giant Stag Beetle, Lucanus elaphus, how to drive.
