Parajulidae

Parajulidae
100 Acre Wood, Winneshiek County, Iowa, USA

I guess it's about time I learned the name of the most common family of millipedes in North America.
It was a wet summer and they were easy to see.
How does one tell an adult? Size?

Good time to ask.
I am completely new to wanting to know something about millipedes. I assume there are photos we can take to help in identification but what would they be?
Thank you.

Identification
MJ, for casual identification, the best shot is a clear dorsal image of a single adult specimen. This works for distinctively colored species, or sometimes based on range.

The next helpful shots would be a macro of the head, and possibly the tail. For positive species level ID, it would often require an image of the male gonopods, but this is very difficult with a live specimen.

Millipedes often (always?) start with 6 legs when born, and add legs/diplosegments as they mature, so counting the number of rings can help you know if they are mature.

Some good reading material is found at bottom of Millipede class main page.
