Its interesting how the same species develops different colour patters. The N. americanus in Ontario are dark green with slight red rings on the segments.I think it would be cool to add more species of millies. I collected the species below in Texas. But there are lots of other cool colors too. N. americanus are beautiful here. There's a pic of one those in the same album.
