Here is a list of articles in the Lepidoptera category of the Biology portal. Lepidoptera is the insect order of moths and butterflies. It is divided in four suborders: Aglossata, Glossata, Heterobathmiina and Zeugloptera. Of these, Glossata is by far most speciose and contains both butterflies (which are further restricted to the clade Rhopalocera) and moths; the other three suborders are far smaller and solely contain moths.
