Broad Necked Root Borer
Dear Bugman!
My Boy Scouts and I found this insect outside my tent at Ockanickon Scout Reservation near Pipersville, Pennsylvania last week (07/08). It was about 2 inches long and what was fascinating was that it appeared to take a defensive posture and extended its “stinger” (propably not the right term but I am rather insect identification challenged!) I found your website and went through the beetle sections. I think it’s a Broad Necked Root Borer, but didn’t see any with the “stinger”. Your opinion, and an explanation of the “stinger” would be greatly appreciated and educational for the Scouts. This is an awesome website! Thank you,

Hi JoAnn,
Your Broad Necked Root Borer, Prionus laticollis, is a female, and the stinger is her ovipositor. She needs a means by which to deposit her eggs deep inside the wood.

is this some kind of Blister Beetle?
Hi, just found your web site – awesome bugs.
I am in Moose Jaw, Saskatchewan and found this beautiful bug on a poppy leaf this afternoon. The only thing that I can find that sort of resembles it is the blister beetle, however it has a dull plain back and only the head parts and some of the under belly are iridescent. Can you ID? Thanks

Hi D,
Your are correct. This is a Blister Beetle. We believe it is in the genus Lytta. We found a match on BugGuide, also from Canada, but it is not identified to the species level. We will contact Eric Eaton to see if he can comment.

Update: (07/28/2008) From Eric Eaton
Hope your lecture at the Getty went well! … Your identifications of the blister beetles are correct to genus. There is no easy way to determine species without having a collection to compare to, or the specimen in hand to run through a “key.” Lots of individual variation in color (and pattern in the case of Pyrota) makes ID impossible from an image alone. … I think that covers all your questions. Keep up the great work.

Hope your still working this site. I have a bug i found in Southern Alberta Canada, could be a *”Broad-toothed Stag Beetle”.* but i dont think it is. If you can, please let me know what this very flat `beetle` might be. see attached 4 pictures. they are not that great cause of bad lighting and he wouldnot stop moving :) oh well. Thanks,

Hi Danny,
Your beetle is actually a Clown Beetle in the genus Hololepta, in the family Histeridae. You can find more photos on Bugguide.

reddish brown stag beetle in Tennessee
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.

2 pictures for you
Found your email addy on the very good site you have on the web. The moth (pictures attached) was on our porch this morning at Payson, Arizona. It was resting on a (lit) lamp shade and has a wing span of 6 inches! I was wondering if you could tell me what kind of a moth it is and wondered if you can use the pic for your site or whatever else. Thanks

Hi Reg,
A few days ago, we received our first photo of this moth, Antheraea oculea, a relative of the Prometheus Moth found in Arizona. That specimen was sent from the Coconino National Forest of Northern Arizona. 50 miles north of Payson. We are copying Bill Oehlke on this reply as he is keeping comprehensive data on species distribution.

Hello Daniel,
Thanks for your answer, i found another one in the garden its the same as the first one but different collour, is it the same?? and the moth on the wall is that one of the catarpilar’s it was 5 cm Kind regards

Hi again Jeannette,
Thanks for sending us another photo of another Puss Moth Caterpillar, Cerura vinula. Many typically green caterpillars change colors, often to brown, red, orange, pink or purple just before pupation. We suspect that is about to happen with this individual. We will address you moth query in a separate email.
