- THYSANURA & ARCHAEOGNATHA
thysanos = fringe)
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).
