The fossil record of hemipterans goes back to the Carboniferous (Moscovian).
The oldest fossils are of the Archescytinidae from the Lower Permian and are thought to be basal to the Auchenorrhyncha.
Fulguromorpha and Cicadomorpha appear in the Upper Permian, as do Sternorrhyncha of the Psylloidea and Aleurodoidea.
Aphids and Coccoids appear in the Triassic.
The Coleorrhyncha extend back to the Lower Jurassic.
The Heteroptera first appeared in the Triassic.

The present members of the order Hemiptera (sometimes referred to as Rhynchota) were historically placed into two orders, the so-called Homoptera and Heteroptera/Hemiptera, based on differences in wing structure and the position of the rostrum.
The order is now divided into four or more suborders, after the "Homoptera" were established as paraphyletic (now the Auchenorrhyncha and the Sternorrhyncha).
The cladogram is based on one analysis of the phylogeny of the Paraneoptera by Hu Li and colleagues in 2015, using mitochondrial genome sequences and homogeneous models.
It places the Sternorrhyncha as sister clade to the Thysanoptera and the lice, making the Hemiptera as traditionally understood non-monophyletic.
However, when heterogeneous models were used, Hemiptera was found to be monophyletic.
The result where Hemiptera was found to be non-monophyletic is likely due to phylogenetic artifacts, such as elevated substitution rates in Sternorrhyncha compared with the other suborders of Hemiptera.
