Collembola

Springtails (class Collembola) form the largest of the three lineages of modern hexapods that are no longer considered insects, the others being Protura and Diplura. 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 insects, which have external mouthparts. There are more than 9000 species.
