La classificazione degli insetti

La classe degli insetti appartiene al tipo degli Artropodi e si divide in due sottoclassi: Atterigoti, cioè sprovvisti di ali, e Pterigoti, ossia alati.
In base poi al tipo di metamorfosi che comporta lo sviluppo postembrionale, gli Pterigoti si suddividono a loro volta in Olometaboli (a metamorfosi completa) e in Eterometaboli (a metamorfosi incomplete di vario tipo).
Agli Atterigoti appartengono gli ordini dei Proturi, Collemboli, Dipluri e Tisanuri. Mentre agli Eterometaboli appartengono gli ordini dei Efemerotteri, Odonati, Blattoidei, Mantoidei, Isotteri, Plecotteri, Fasmoidei, Ortotteri, Deramtteri, Corrodenti, Mallofagi, Anopluri, Tisanotteri, Emitteri. Ed infine gli ordini che caratterizzano gli Olometaboli sono i Neurotteri, Mecotteri, Tricotteri, Lepidotteri, Ditteri, Afanitteri, Coleotteri, Imenotteri.
