[1][2] The cosmopolitan springtail measures about 2 mm in length.

Its color consists of a yellow or white background with dark pigment forming transversal bands along the third segment of the thorax and the segments 2 to 6 of the abdomen.

The fourth segment of the abdomen has a U- or 11-shaped pattern that easily distinguishes this species from others in the genus Entomobrya.

[3] The cosmopolitan springtail is found in temperate and polar regions of North America and Europe.

[5] The hemolymph of the cosmopolitan springtail is rich in antifreeze compounds, allowing it to withstand the very low temperatures of winter.
