- 💡 The body length of 10–20 mm for this woodlouse family is smaller than the diameter of a Korean 500-won coin (26.5 mm) (Comparison, family-wide figure).
- 💡 Because this group prefers dark and damp environments, it is easy to encounter in moist shade (National List of Species of Korea family description).
- 💡 When populations grow, they sometimes chew on the roots or stems of garden plants in flowerbeds and pots, causing damage (National List of Species of Korea family description).
