Colorado Springs, El Paso County, Colorado, USA
April 1, 2008
Size: about 1.5 inches long
When I looked through your collection of millipede photos, I didn't see one like this, with long legs in the rear. About 1.25 - 1.5 inches in length.

Moved from Centipedes.

Looks more like a centipede to me, which would explain finding no match in millipedes. I don't know much about them, but Stone Centipedes (compare below) might be a good place to start.

Well, I'm just a beginner at this, so maybe I get confused easily,
but it was my understanding that a millipede has two pair of legs per body segment, and a centipede has one pair per body segment.
When I count legs and body segments on this little creature, and do the math, it comes out Millipede.
Or am I confused?

I think perhaps some of the body segments are hidden
at least from above and at this angle. The other image I linked has the same characteristic.

stone centipede
This is a centipede. Milipede legs do not get gradually longer toward the rear of the body as seen here, and they do not have the forcipules, the "fangs" along the side of the head visible in the photo above.

15 pairs of legs say stone centipede, but I can't tellyou more than that.

Thanks, Sara.
