Summary

The family Glomeridae encompasses a diverse group of pill millipedes known for their ability to roll into a ball, aiding in defense against predators. With close to 300 species across approximately 30 genera, they play important ecological roles in nutrient cycling.

Physical Characteristics

Glomeridae are characterized by their rounded body shape and the ability to roll into a ball, similar to pill millipedes. They usually have a hard, calcified exoskeleton and can exhibit various colors, including brown, black, and yellow shades.

Identification Tips

Look for the rounded form of the body and the distinctive ability to curl into a ball. They typically have segments with visible sutures and may present a shiny appearance due to the hard exoskeleton.

Habitat

Often found in leaf litter, under rocks, and damp environments such as forests, grasslands, and sometimes caves.

Distribution

Predominantly found in North America, Eurasia, and parts of Africa.

Diet

Detritivorous, feeding on decaying plant material, fungi, and leaf litter.

Life Cycle

Life cycles typically involve several molts, with a focus on juvenile stages that resemble adults.

Reproduction

Reproduction is sexual; males typically engage in courtship behaviors, and fertilization occurs internally. Females may lay eggs in moist substrates.

Predators

Predators include various birds, mammals, and other arthropods that consume small invertebrates.

Ecosystem Role

Play a vital role in the decomposition process by recycling nutrients back into the soil, aiding in soil formation.

Collecting Methods

  • Hand collecting from leaf litter
  • Trap collection under rocks or logs

Preservation Methods

  • Ethanol preservation
  • Freezing
  • Drying

Evolution

Belong to the class Diplopoda and exhibit adaptations that reflect their terrestrial lifestyle, such as desiccation resistance and detritivorous feeding behaviors.

Misconceptions

Often mistaken for insects due to their segmented bodies, but they are more closely related to other arthropods like spiders and scorpions.
