The next view shows the head, with dark eyes and segmented antennae:
This is a very large millipede with wonderful pink and silver stripes. I'd estimate it was ~2.5 inches long (7 cm) and ~1/4 inch (0.6 cm) in diameter.
While trying to identify this millipede, I found an Annotated Checklist of the Millipeds of California published by Rowland Shelley in 2002. Do you want to guess how many species and subspecies of millipedes there are in California? (The answer is below the next image.)
There are 226 species and subspecies of millipedes in the Golden State. Whew! That's a lot of millipedes (and a lot of little legs running around California!).
Unfortunately, the list didn't help me identify this particular millipede, so if you know which species it is, please don't hesitate to contact me.
