Summary

Spirobolidae is a large family of millipedes known for its substantial size and detritivorous diet, contributing to ecosystem health through nutrient recycling.

Physical Characteristics

Length of 4‒12 cm; includes some of the largest millipedes in North America, much longer and wider than similar-looking Julida.

Identification Tips

Differences in size and morphology compared to Julida; consider habitat and geographic distribution.

Habitat

Found primarily in forests and leaf litter; prefers moist environments.

Distribution

Regions include Southern California, Florida, northern Texas, and parts of Canada (e.g., Quebec) to southern Ontario and northeastern Texas.

Diet

Detritivorous; feeds on decomposing organic materials and leaf litter.

Life Cycle

Life cycle involves several molts; typical millipede growth and maturation phases are observed, including egg laying by adults.

Reproduction

Reproduces through direct mating; females lay eggs in soil or leaf litter.

Predators

Birds, small mammals, and insects such as predatory beetles.

Ecosystem Role

Plays a critical role in decomposition and recycling nutrients in the ecosystem.

Economic Impact

Not considered economically significant; may have positive effects on soil health but can be overlooked.

Collecting Methods

  • Hand collection in the field
  • Pitfall traps
  • Sifting leaf litter

Preservation Methods

  • Ethanol preservation
  • Drying specimens
  • Freezing for morphological study

Misconceptions

Often confused with similar-looking Julida species, particularly in terms of size and habitat.
