Orders - THYSANURA & ARCHAEOGNATHA
(Greek, thysanos = fringe)
Common Names: silverfish, firebrats
Distribution: Cosmopolitan

Description
Although these orders are not closely related to one another (the Thysanura is more closely related to the winged insects than to the Archaeognatha), they are both called bristletails and they are similar in general shape. Archaeognatha (jumping bristletails) are more robust and have larger eyes than Thysanura (bristletails).
