Millipedesmillipede, but what species?
Hi bugman,
I love the website!!! I work for a non-profit environmental organization in Southwestern PA. We took a picture of this beautiful millipede while conducting field work one day. We are inducting it into our photo library but want to make sure that it is correctly identified as either native or exotic/invasive. Can you tell me what species of millipede this is and if it is native to the eastern US or, more specifically, to PA.
Thanks a lot,

Hi Kylie,
Native and in your range. This is an American Giant Millipede, Narceus americanus. According to BugGuide, the range is “Southeastern US, north to Ohio, and west to Texas.”
Update: (01/20/2008) Millipede IDs
1/25/06 . Narceus americanus (Beauvois)

Their range appears now to extend as far north as Parry Sound, Ontario. We recently found several examples on a canoe trip through mixed hardwood & hemlock forest in that area.
