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.
Homidia pentachaeta is a species of soil-dwelling springtail belonging to the family Entomobryidae. It is only known from its type location in the vicinity of Nanjing, People's Republic of China.
