Explanation of Names

Author: Krausbauer, 1898

Range

Nearctic, very common in Europe, introduced.

Remarks

Species has sexual dimorphism (quite rare in entomobryomorph Collembola): thickening of the outer side of the 2nd antennal segments is typical of males of this species.

This species is adapted to live on the water surface: note the hypognath head (with mouth opening directed downwards to the watersurface), typical for water surface film dwellers (see also Podura aquatica). Note also the broad dentes which prevent piercing the water surface film when the specimen needs to jump. Comments by Frans Janssens.
