Vermont millipedes have two basic body plans -- "round-backed" and "flat-backed".
This is Rudiloria trimaculata (it has no common name) - a member of the flat-backed group.
The most common round-backed millipede in Vermont is the North American Millipede (see my previous post for a picture https://champlainislandsnature.blogspot.com/2016/05/north-american-millipede.html)
Millipedes are believed to be one of the oldest groups of insects -- being one of the first organisms to inhabit the land. Today, they can be found under the leaf litter eating decaying organic matter.
They have a variety of defense mechanisms. One of which is a hard "shell". If you look closely at the picture, you will see that this millipede most likely had a encounter that left a few dents in the fenders and a few scratches in the paint. It didn't seem any worse for wear.
