We have what we believe is a cottonwood stag beetle larvae. He is over 2 inches long and has large pinchers. We found him buried in the wood chips at the playground where we have seen the really big cottonwood stag beetles and we are assuming for its size and location that is what we have. My kids really want to “raise” it. We have kept it in a jar with wood chips for about 3 months. We occasionally add a little water. I can’t find anything about it’s lifecycle. What else can we do to ensure a successful metamorphosis in the spring/summer. We check every few days for movement through the glass, so far so good.

Dear Jr entomologists,
You are our first posting of the New Year after returning back to the office today.  We agree that this is most likely a Cottonwood Stag Beetle Grub since you have found adults in the vicinity.  Your individual looks like the Stag Beetle Grub pictured on BugGuide.

Hi Bugman,
Wondering if you can help. I found this impressive specimen on my back driveway last week. Never seen it before here in Northern New Jersey. Although it was on the paving blocks, it was right next to the edge (see Belgium block ending in one pix), which is right next to lavender plants.
Hope it is just a garden variety, and not something of greater concern…
Thanks for any help….

Dear Mary,
This is a male Reddish Brown Stag Beetle.  Males have much larger mandibles than females.

Daniel,
Wow, thanks for the quick reply and for great information.  I checked out other posts about this beetle on your website and learned a lot.  Nice to know it is not destructive.  There is a pile of old firewood nearby, which may have served as the nursery.
You have a wonderful and helpful website, and hope to return to it in the future.
thanks again,
Mary

Hi! This little guy was on my patio yesterday. I saw one other just like it years ago. I can’t quite find it in all the images around. I thought maybe a pseudoscorpion but this guy was well over an inch big. I’m really curious what it is.
Thanks!

Giant Stag Beetle

Dear Paula,
This beauty is a male Giant Stag Beetle.  They are attracted to lights.

Wow.  Thanks!  How can you tell it’s a male?  (Yes, I realize I am opening the door to some mischief here).

Males have the impressive, mandibles that resemble a stag’s antlers.  Females, like this individual posted to BugGuide, lack the oversized mandibles.

Where is the work yard?  Zimbabwe?  Belize??  Other???

Ed. Note:  The location field in our standard form is meant to give us a general indication of where in the world the sighting occurred.  Locations like “bathroom” or “work yard” are not very helpful.  As most of our identification requests from May through October come from North America, we suspect this is case with this Stag Beetle, which we identified to the family level because of the shape of the antennae, which is illustrated on the BugGuide site.  Most of the head is obscured by what appears to be a spider web.  Though Tiarone has indicated “i am from the uk” there is no indication that the sighting occurred there.  If this is a North American sighting, it might be Lucanus placidus which is pictured on BugGuide.
