Entomobrya nivalis, the cosmopolitan springtail, is a species of slender springtails in the family Entomobryidae. [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. [3] [4] 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 loose portions of bark. [5]
The hemolymph of the cosmopolitan springtail is rich in antifreeze compounds, allowing it to withstand the very low temperatures of winter. [5]
Entomobryidae, sometimes called "slender springtails", is a family of springtails characterised by having an enlarged fourth abdominal segment and a well-developed furcula. Species in this family may be heavily scaled and can be very colourful. The scale-less Entomobryidae are commonly caught in pitfall traps around the planet, and also occur in canopy faunas high up in trees. There are more than 1700 described species in Entomobryidae.
The Entognatha are a class of wingless and ametabolous arthropods, which, together with the insects, makes up the subphylum Hexapoda. Their mouthparts are entognathous, meaning that they are retracted within the head, unlike the insects. Entognatha are apterous, meaning that they lack wings. The class contains three orders: Collembola, Diplura and Protura. These three groups were historically united with the now-obsolete order Thysanura to form the class Apterygota, but it has since been recognized that the hexapodous condition of these animals has evolved independently from that of insects, and independently within each order. The orders might not be closely related, and Entognatha is now considered to be a paraphyletic group.
The Entomobryoidea are a superfamily of springtails (Collembola), tiny hexapods related to insects. In the modern sense, this group is placed in an order called Entomobryomorpha.

Willowsia buski, the damp grain springtail, is a species of slender springtail in the family Entomobryidae. It is found in abundance throughout North America and Europe, and likely has a cosmopolitan distribution. It can sometimes be found infesting stores of dry goods that have become contaminated with high moisture, giving rise to the name "damp grain springtail".
