Appearance
The cosmopolitan sprintail 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 adbmonen. The fourth segment of the adbomen has a U- or 11-shaped pattern that easily distinguishes this species from others in the genus ''Entomobrya''.
Habitat
The cosmopolitan springtail is found in temperate and polar regions of North America and Europe. Juveniles usually live in the leaf litter of forests and migrate upward after becoming adults, living among lichens growing on trees. During winter, they shelter under lose portions of bark.The hemolymph of the cosmopolitan sprintail is rich in antifreeze compounds, allowing it to withstand the very low temperatures of winter.
