Entomology (Study of Bugs)/mystery bug


Greetings, Eric, from a former Coloradan living in Eugene, Oregon. This morning, sitting on the front steps of our 1927 Craftsman-style house, I looked down into the ivy alongside and was struck with the sight of a jet black bug with a striking bright white spot in the middle of its back. I couldn't tell if it had wings. It was at least 3/4" long, not at all slender. Very black with a very white spot in the middle of its back maybe 1/16" in diameter. I turned around to call to my wife for a camera and, yep, when I looked again, it was gone. I'm quite sure I greeted it; I always talk to spiders I find inside and take them outside to our grape vine.
Thanks, Eric, for any light you can shine. Ever been to Carbondale (CO)? I went to school up there in the High Country and miss it, though not as much as I do the ocean when I'm there for long!


There are many insects I can think of that would fit your description, so I am afraid I can't help you without at least an image.

You may want to look at the Kaufman Field Guide to Insects of North America .  We went to great lengths to include conspicuous insects from your area in that book.

No, have not been to Carbondale.  I've only been here since October, 2011, though, so....

Meanwhile, it is only fair to warn you I went to Oregon STATE. :-)

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
