About Globular Springtails: the wider group

Order-level background for Symphypleona, the group containing Janusius sylvestris. Species-specific details appear above.

Group overview

Symphypleona (globular springtails) includes ~1,200 described species. These round-bodied springtails are found on vegetation surfaces, in soil, and even on water surfaces where they can skate using surface tension.

Ecological role of the group

Symphypleona feed on fungal spores, pollen, algae, and decaying plant material. They play critical roles in nutrient cycling and are among the first colonizers of disturbed or newly formed soils.

Economic and practical significance of the group

Globular springtails are important bioindicator species used in ecotoxicology testing for soil contamination. ISO standard soil toxicity tests use springtail species like Folsomia candida.

Recorded sources for this group: ISO ecotoxicology standards, soil biology research. Imported estimates may describe particular regions or reporting periods.
