1st Tennessee Arthropod--Red-Sided Flat Millipede

This beauty is the Leach's Millipede (Sigmoria latior). While staying in Townsend, TN I was hoping to find numerous insects, and while I didn't find huge numbers of insects or other arthropods; the ones that I did find were interesting. This gorgeous millipede was crawling across the deck of the cabin we were staying at. I had just reluctantly left the comfort of the hot tub, when I noticed this thing crawling quite rapidly across the porch. At first glance I thought it was a caterpillar, imagine my surprise to discover what it really was. I was little concerned about handling it, as red is usually a warning coloration and I know that many millipedes exude a chemical secretion that can cause burning or skin discoloration. I do not know if this particular species has that ability, but I didn't want to take the chance. I captured him and plan to use him as an exhibit arthropod for our upcoming Insect-O-Rama event. This particular specimen was approximately 3 inches in length, and once again I am unsure if this is as big as they get or if bigger ones can be found. About the only information I could find on them states they prefer the rotting wood of hardwood trees. Associated with long leaf pine woods and oaks. They are common, but this was the only one I could find, and believe me I looked frequently around our cabin.This dark brownish-black millipede was laying on a walking trail near the Cades Cove area of the Smokey Mountains. A Harvestman was munching down on the unfortunate victim. The Harvestman (a.k.a Daddy Longlegs) were HUGE in this area. WAY bigger than anything we have in NWMO. I am unsure of the species of this Millipede, but I believe it is Narceus americanus. These are one of the biggest millipede, if not the biggest in the Eastern United States.

  1. The Leaches Millipede is a real beauty. In Hong Kong in an old graveyard I once came across a millipede that was completely red - a real surprise.
