Quick Summary

The genus Julus is a widely distributed group of millipedes belonging to the family Julidae. Millipedes, in general, are arthropods of the class Diplopoda, known for their cylindrical bodies composed of many rings, with most segments bearing two pairs of legs. They are found worldwide and primarily consume decaying plant matter.12

The family Julidae includes millipedes with cylindrical bodies of over 30 rings and multiple eyes clustered together. A common example is Julus terrestris, a species native to Europe that has also been introduced to North America. Millipedes typically defend themselves by coiling up and, in many cases, secreting a toxic liquid or gas.32
