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. The class contains three orders: Collembola (springtails, 9000 species),[3] Diplura ("two-tail", 1000 species)[4] and Protura ("first-tail", 800 species).[5][1][2] These three groups were historically united with the now-obsolete order Thysanura to form the class Apterygota, but it has since been recognized that the hexapodous condition of these animals has evolved independently from that of insects, and independently within each order.[6] The orders might not be closely related, and Entognatha is now considered to be a paraphyletic group.[2]
