1. Insects (âHexapodaâ) are not a sister group of crustaceans, as was indicated by some molecular studies. Nor are they the sister group of myriapods, the traditional arrangement supported by morphology.Instead, insects are nested within crustaceans (see Figure 1).n the same sense that birds are dinosaurs, then, insects are crustaceans. 2. The sister group of insects within crustaceans comprises two rather obscure taxa that were long thought to be primitive: the cephalocarids and the remipedes.
