Plumatyla humerosa is a millipede species found in mines, as well as lava tube and limestone caves of northern California and south-central Oregon.{{cite journal|last1=Shear|first1=William A.|last2=Richart|first2=Casey H.|last3=Wong|first3=Victoria L.|title=The millipede family Conotylidae in northwestern North America, with a complete bibliography of the family (Diplopoda, Chordeumatida, Heterochordeumatidea, Conotyloidea)|journal=Zootaxa|issn=1175-5326|doi=10.11646/zootaxa.4753.1.1|volume=4753|number=1|url=https://pubmed.ncbi.nlm.nih.gov/32230402/|date=2020-03-19|pages=zootaxa.4753.1.1|pmid=32230402|s2cid=214749632}} It belongs to the family Conotylidae. The millipede is likely a troglophile with a white carapace and observed in lava caves though it may inhabit crevices as well.{{cite web|last=Skeels|first=Matt|title=Cave Inhabitants of Oregon|website=Oregon High Desert Grotto|url=http://ohdgrotto.caves.org/fauna/cave-inhabitants-of-oregon|date=2019-09-27|access-date=2022-03-24}}{{cite journal|last1=Elliott|first1=William R.|last2=Reddell|first2=James R.|last3=Rudolph|first3=D.

Taracus marchingtoni has been observed feeding on P. humerosa within cave habitat.{{cite journal|last1=Shear|first1=William A.|last2=Warfel|first2=Joseph G.|title=The harvestman genus Taracus Simon 1879, and the new genus Oskoron (Opiliones: Ischyropsalidoidea: Taracidea)|journal=Zootaxa|issn=1175-5326|doi=10.11646/zootaxa.4180.1.1|volume=4180|number=1:2|url=https://www.biotaxa.org/Zootaxa/article/view/zootaxa.4180.1.1|date=2016-11-02|pages=1–71|pmid=27811667|url-access=subscription}}
