I found this on my walk this morning (October 3, 2015) on a nature trail on the outskirts of town in southeastern New Mexico. It was in the 90’s last week but has been cool and rainy the last few days. He / She did not look familiar. Every time I tried to get a close up, it would circle to the far side of the branch. It is black and yellow on its shield-shaped back with black and yellow bands on its underside. I searched your site and BugFinder for black and yellow beetles, but I didn’t find any that seemed to match. I love your site and the story behind it. Thanks for putting in all the time and effort.

Dear Curious,
We located this image on BugGuide that matches your Metallic Borer Beetle or Jewel Beetle from the family Buprestidae.  The posting states that the collector:  “gave the specimen to New Mexico State University as they only had three of this species.”  Your individual was found on an Acacia, and according to BugGuide:  “Larval host unknown, adults on Acacia, Prosopis.”  This really is a beautiful Jewel Beetle and your observations indicate that the species has excellent eyesight.

I found your response on the website. Thank you, again, for your work. It was a kick to learn that I was probably right when I thought the beetle was unusual, if NMSU only had three in its collection. I found and photographed another bug on that same walk, but I am still looking online to see if I can identify it, If I can’t, I may forward it to you for your assistance.

We apologize if we did not write back to you directly as that is our usual method of responding upon posting a submission.

No apology necessary!  I knew to look on the website and found my submission there faster than I thought I would.  I am surprisingly proud that I found an unusual specimen (and I’m even happier I did not find the human louse as did someone else whose picture was posted on the same day as mine).  I just wanted to say thank you and didn’t know how to post directly to the website.  My technical knowledge is too antique to figure that out, so I responded directly to your email.  My apologies if I confused you.
I still haven’t had any luck finding the other bug I photographed on the same walk, so I will probably submit that, too.
