The millipedes living in my neck of the woods are about three inches long and round, with pretty stripes marking the edge of each segment. They have dainty antennae and feet that will tickle if you let them crawl up your arm. Some folks think millipedes have 1,000 legs, but they don't. What they do have is 2 pair of legs per segment. Centipedes have one pair of legs per segment, and tend to be flatter - and faster.
Millipedes tend to spiral when they die, and their colors fade. But, even dead, they are cool to observe. For one thing, their faces look like they have smiles. And for another, you can see how the legs attach.
This week ~ look for bugs with lots of legs. Maybe you'll find roly-polies (pill bugs) or centipedes or millipedes, or daddy longlegs.
Give it a name. Mine is named Millie.
Spend some time watching your critter. How do the legs attach to the body? How fast does it move? What does it look like when you put your eyes at ground level?
Draw a picture or take a photo so you can continue to study your leggy critter.
