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 (notably Entomobrya nivalis, very common throughout Europe if not the Northern Hemisphere). There are more than 1700 described species in Entomobryidae.
