Millipede: Brachycybe rosea

Dear Romel,
We believe we have correctly identified your Millipede as
Brachycybe rosea based on images posted to BugGuide where it states:  “Found typically under rotting oak lying on soil. I found these both in Cool (El Dorado County) and Fair Oaks (Sacramento County) but only collected in Cool.”

I have looked everywhere but I can’t seem to identify this millipede. Can you help?

Iron Worm

Iron Worm

Dear Frank,
We quickly identified your Millipede as a North American Millipede,
Narceus americanus-annularis-complex, thanks to images posted to BugGuide.  According to BugGuide, it is:  “Usually dark reddish-brown with red edges on each segment. The most commonly-seen large millipede in its range.”  Our favorite bit of information on BugGuide is that this Millipede is commonly called an “Iron Worm.”

Dear Bugman,
I found this worm-like caterpillar bug in our toilet coiled up and was concerned it came out of my husband who had used the restroom prior to me. We put it in a plastic cup and it is still moving around, spitting up black ink here and there. Thoughts?!

Millipede found in toilet

Dear Concerned,
You should teach your husband to flush.  This looks like a Millipede, and we suspect it fell into the toilet, but we have researched some Soil Centipedes that are reported to crawl up human gastrointestinal tracts.

Thank you for your response!  Husband seems to be OK and millipede is safely outside of our home’s jurisdiction.

What's Eating the Lichen????

What’s Eating the Lichen????:  Pincushion Millipede

Dear LPainne,
Your image is beautiful, and we have no idea what this is, except that it looks larval.  We are posting your image and we hope that with the help of our readership, we will be able to provide an identification soon.

Update:  Pincushion Millipede
Thanks to a comment from Cesar Crash and a confirmation from Christopher Taylor, we now know that this is a Pincushion Millipede or Fuzzy Millipede or Bristly Millipede in the genus
Polyxenus which is pictured on BugGuide where it states:  “Their typical habitats are generally described as litter and bark, also commonly collected from rocks and old walls” and “They are diurnally active, feeding on algal films and lichens, often in warm and dry conditions and direct sunlight.”

Hey there Bugman!
I’m currently doing habitat research in pill bugs for my animal behavior class and came across this little fella during my observations. I’ve never seen a centipede with this coloration around my area. I’m too interested to wait till I get back to college to ask our entomologist. Please help!

Millipede:  Euryurus leachii

Dear Russ,
This is not a Centipede, but a Millipede which has two pairs of legs on each body segment.  We believe it may be
Euryurus leachii based on this image we found on BugGuide.  The information page on BugGuide states:  “This is Euryurus leachii (Gray), a very colorful representative of the endemic North American family Euryuridae (Polydesmida). There are 2 genera in this family, Auturus & Euryurus, and the species occurring in Indiana is E. leachii. These are among the very few North American millipeds that one can deliberately try to find, because they occur almost exclusively in association with decaying hardwood logs & stumps near water sources ()creeks, seepages, etc.). They are rarely found in just leaf litter and almost never in association with pines. I’ll bet the log they found it under was an oak or another hardwood. (Dr Rowland Shelley).”  There are no reported sightings from Tennessee on BugGuide, but there are sightings from Illinois, Indiana, Ohio and nearby Kentucky.

I found this in my son’s room. I’m just wondering what it is and is it dangerous. He is 1 and puts everything in his mouth.

Possibly Rusty Millipede

Possibly Rusty Millipede

Dear Karen,
This is a Millipede in the class Diplopoda, and it looks like it might be a Rusty Millipede,
Trigoniulus corallinus, which BugGuide states is:  “Non-native. Apparently from Thailand and Myanmar. Also present in the Caribbean.”  BugGuide also states:  “To discourage predators, millipedes coil into a protective spiral, or roll into a defensive ball; many emit poisonous or foul-smelling substances. Many bright-colored/patterned millipedes (image below) secrete a compound containing cyanide.”

Ok great so it is nothing I should be concerned about being poisonous to my son?

To the best of our knowledge, cyanide is considered a poison, though we suspect the quantity released by a Millipede would be more likely to cause any potential predator, including your son, to spit it out immediately because of the foul taste.  We do not want to go on record stating it is harmless.
