Springtails (class Collembola) form the largest of the three lineages of modern hexapods that are no longer considered insects.Although the three lineages are sometimes grouped together in a class called Entognatha because they have internal mouthparts, they do not appear to be any more closely related to one another than they are to all insects, which have external mouthparts.
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 Entomobryomorpha are one of the three main groups of springtails (Collembola), tiny hexapods related to insects. This group was formerly treated as a superfamily, the Entomobryoidea. They can be best distinguished from the other springtail groups by their body shape. The Symphypleona are very round animals, almost spherical.
The Entognatha are a class of wingless and ametabolous arthropods, which, together with the insects, makes up the subphylum Hexapoda. [1] [2] Their mouthparts are entognathous, meaning that they are retracted within the head, unlike the insects. [1] Entognatha are apterous, meaning that they lack wings.
Even a springtail drifting on the surface tension of a layer of water often can jump successfully. Furthermore, the furcula is effective in environments typical of Collembola; most predators of springtails are small and many have little power of sight, so if the prey leaps in time, the chances are that from the hunter's point of view, it simply ...

The order Symphypleona, also known as the globular springtails, is one of the three main groups of springtails (Collembola), tiny hexapods related to insects. When the springtails were still believed to be an order of insects, the Symphypleona were ranked as a suborder. They can be best distinguished from the other springtail groups by their ...
