Hi there!
I took a picture of this handsome fellow in mid-October at the Lower Twilight Campgrounds on Mount Graham in the Pinaleño Mountains in southeastern Arizona. He was about an inch and a half long. We were about 7,400 feet up, the temperature was 65-75 degrees Fahrenheit and the vegetation was medium-thick ponderosa pine.
Thanks so much for your help!

Metallic Borer Beetle

Metallic Borer Beetle

Hi Kristin,
Thank you for being intelligent enough to indicate that this sighting did not happen this week.  You would be surprised at the number of folks who neglect to tell us that information because many times the actual month of a sighting is quite significant.  This is one of the Metallic Borer Beetles or Jewel Beetles from the family Buprestidae, and we believe it is the Western Sculptured Pine Borer,
Chalcophora angulicollis.  Though there are five member in the genus that look very similar, the only one that is reported from Arizona is the Western Sculptured Pine Borer.  According to BugGuide, it is found in “Coniferous forests” and its host trees include:  “hosts: various Pinaceae, incl. Abies concolor, A. grandis, Pinus ponderosa, Pseudotsuga menziesii(2); adults feed on leaves” which is very consistent with your sighting.  At least on BugGuide, sightings have been reported from May through July, so your October sighting is somewhat uncharacteristic, however BugGuide does offer the disclaimer that “Range and date information may be incomplete, overinclusive, or just plain wrong.” INaturalist also includes an August 26 sighting.  We suspect your altitude might have some bearing on the sighting occurring in October.

Daniel,
Awesome!!! Thanks so much for the quick reply and all of the excellent info.
My husband’s a Ph.D. student in evolutionary biology, and he’s done a little bit of collecting in Drosophila, Scaptomyza and Lycaenidae back before his current project. He’s given me a pretty good idea that more info is always better for an accurate ID.
Thanks again for your help!
Kristin

What an interesting combination of insects to have been collected by your husband.  Is he aware of the book Nabokov’s Blues which covers the two authors’ expedition to South America to discover new species of Lycaenidae?  They then classified them based on some theoretical papers written by the novelist and amateur lepidopterist, Vladimir Nabokov, which had been lost for nearly fifty years.  As it turned out, Nabokov’s theories held true and many new species were named after characters from his books.

Daniel,
I’m sure he’s heard of “Nabokov’s Blues” at the very least — he worked with Naomi Pierce (http://harvardmagazine.com/2001/07/a-life-with-lycaenids-html) for a few years out of undergrad. But we don’t have a copy around the house! He’s got a birthday coming up … thanks so much for the idea! :-)
Have a wonderful day.
Kristin

Nabokov’s Blues is a highly entertaining read and we believe it will make an excellent birthday present.

This guy may work for the NSA. Look at his huge eyes. He makes a very audible tick sound when he moves. He’s about the size of the last two joints on my little finger. I discovered him while taking a few wacks at a dead and diseased southern maple with an axe. His hole is not far from the rotted center base of the tree. He has skinny legs. The location is about a mile north of theNaval Air Station near Pensacola.

Dear Bob,
This is an Eyed Elater, one of the Click Beetles that is capable of righting itself when it finds itself on its back, by snapping its body at the joint between the thorax and the abdomen, producing an audible “click”.  We are especially happy to receive your photo of the hole of an Eyed Elater.

Well, thank you Daniel. You guys are amazing! I submitted my photos at 6PM Sunday night and you answered by 1AM. Those creepy crawlies must keep you up all night. Your website is what they must have envisioned when they invented the internet. Thanks, Bob

Thanks for your kind comment Bob.  We just posted one final posting prior to going to sleep, and that was your submission.  We are several hours earlier in California, so we were not up all night responding to the increasing number of requests we are getting now that spring is upon us.

Dear Leonardo,
Back in 2003, we received a photo of this Metallic Wood Boring Beetle from the family Buprestidae, and we eventually identified it
Capnodis cariosa thanks to the assistance of Mardikavana.

I saw this trippy-looking beetle sunning itself on my porch this afternoon. I’ve never seen one like it before. It’s about 1 1/2” long with blue feet and iridescent blue on its back. Very beautiful.

Jewel Beetle: Lampetis webbii

Hi Tamara,
We were going to post your photo with a family identification only, but as luck would have it, we quickly identified the species as well.  This is a Metallic Borer Beetle or Jewel Beetle in the family Buprestidae, and when we did a web search of the family name and Arizona, we found Rollin Coville’s Buprestidae Gallery which had some examples of the blue legged
Lampetis webbiiBugGuide has some additional photos and the information that the larvae feed on Palo Verde.

Update
After posting, we realized we had several similar looking beetles from the same genus in our archives, so we would not discount that this might be Drummond’s Blue Footed Bup,
Lampetis drummondi.
