Are also called hexapods?
Hexapods are so called because they have a thorax with three pairs of legs. Most other arthropods have more than three pairs of legs. Alternatively, the Hexapoda could be eliminated because they are polyphyletic, the Insecta promoted to sub-phylum, and the minor groups become incertae sedis.
Which animals are hexapods?

Is Hexapoda an order?

When did hexapods appear?

How many Hexapoda classes are there?
HEXAPODA. This taxonomy of the Subphylum Hexapoda has 3 classes. Brusca and Brusca (2003) lump the collembolans, proturans and diplurans into a single class that they call Entognatha.
Why are hexapods not insects?
They don’t have external mouthparts, so are sometimes called “entognaths”, meaning “inside mouth”. Additionally, none of them have wings. They used to be considered insects, but all insects share a common ancestor and thus pinch neatly off the tree of life as one group, leaving the entognaths behind.
