Guides

  • Entomobrya nivalis

    Cosmopolitan Springtail

    Entomobrya nivalis, commonly known as the cosmopolitan springtail, is a globally distributed species of slender springtail in the family Entomobryidae. Adults measure approximately 2 mm in length and display distinctive coloration with dark transverse bands on a yellow or white background.
