Mystery Solved

For years, as I've walked through the Indiana Dunes, I've wondered what type of creature would leave the wavy lines in the sand near the beach. The other day I came across this guy weaving its way through.

This millipede was beautiful; almost blue with all those tiny red legs and coordinating red antennae. It was built to travel the dunes too---racing over the sand as fast as I could snap its picture.
