Answer:
Archaeognatha are small insects with elongated bodies and backs that are arched, especially over the thorax. They have three long tail-like structures, of which the lateral two are cerci, while the medial filament, which is longest, is an epiproct. The antennae are flexible.
Explanation:
Characteristics of Archaeognatha are:-
- Their primitive mandibles have only one point of articulation with the head. In all other insects there are two.
- They have compound eyes that meet at the top of the head, and this can be used to separate them from Thysanura, which have large eyes that don’t meet at the top of the head.
- Archaeognatha can jump as high as 12 inches into the air by using their tails.
