Eumetabola is an unranked
clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, ...

Neoptera. Two large unities known as the
Paurometabola and Eumetabola are probably from the
adelphotaxa of the
Neoptera after exclusion of the
Plecoptera
Plecoptera is an order of insects, commonly known as stoneflies. Some 3,500 species are described worldwide, with new species still being discovered. Stoneflies are found worldwide, except Antarctica. Stoneflies are believed to be one of the mo ...
. The monophyly of these unities appears to be weakly justified.
Eumetabola has the highest number of species of any clade. According to a
phylogenetic analysis, the Eumetabola clade originated 390-350 million years ago, in the
Late Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, wher ...
