Archaeognatha is an order of the class Insecta, also known as the jumping bristletails, which have previously been combined with the order Thysanura, or bristletails, so named because of their three-pronged tails. An alternate name is the Microcoryphia from micro, small and coryphia, head. They are among the least evolutionarily changed insects, appearing in the Devonian period along with the Arachnids. The name Archaeognatha is derived from Greek. Archaeos meaning ancient is combined with gnatha meaning jaw. There are approximately 350 species in the two families. They are distributed worldwide, and unusual in the insect world in that they can even be found in the Arctic where they live in leaf litter and rock crevices.
There are no current species at conservation risk.
