Julids

Julids are a family of millipedes belonging to the order Julida. They are characterized by their cylindrical, elongated bodies which are typically segmented and often possess distinct coloration. Julids are commonly found in soil and leaf litter, where they play a role in decomposition. They are detritivores, feeding on decaying organic matter such as dead leaves, wood, and fungi. Their chewing mouthparts are adapted for breaking down this material.

The Julida order is one of the largest and most diverse among millipedes, with numerous genera and species found across various continents. They are particularly abundant in temperate regions. When threatened, many julid species can curl into a tight spiral, protecting their softer undersides. Some species also possess defensive glands that can secrete noxious substances to deter predators. Reproduction in julids typically involves the male transferring sperm to the female, after which the female lays eggs, usually in soil or decaying wood. The young hatch as small millipedes with only a few segments and gradually add more segments as they molt and grow. Their common name, "julid," is derived from the Roman goddess Julia.
