About Flat-backed Millipedes: the wider group

Order-level background for Polydesmida, the group containing Harpaphe haydeniana. Species-specific details appear above.

Group overview

Polydesmida (flat-backed millipedes) is the largest millipede order with ~3,500 described species. Many species produce hydrogen cyanide (HCN) as a chemical defense - a strategy unique among arthropods.

Ecological role of the group

Flat-backed millipedes are major leaf litter decomposers in forest ecosystems, recycling calcium, nitrogen, and other nutrients. Their fecal pellets contribute significantly to soil formation and humus production.

Economic and practical significance of the group

Millipedes are generally beneficial decomposers but can occasionally damage seedlings and soft fruits in gardens. Some tropical species cause skin irritation through their cyanide-based defensive secretions.

Recorded sources for this group: Myriapod research, soil ecology. Imported estimates may describe particular regions or reporting periods.
