Hymenopterida

Hymenopterida is a superorder of holometabolous (metamorphosing) insects. As originally circumscribed, it included Hymenoptera and the orders in Panorpida (Mecoptera, Siphonaptera, Diptera, Trichoptera and Lepidoptera).[1] However, more recent studies find Hympenoptera as sister to the other members of Holometabola and the superorder is restricted to Hymenoptera.[2]

Evolution

The following phylogenetic tree shows the internal relationships of the superorder as a clade of Hymenoptera and the orders that comprise Panorpida.[3][4]

Endopterygota
Neuropteroidea
Hymenopterida

Hymenoptera

Panorpida
Antliophora

Diptera (true flies)

Mecoptera (scorpionflies, hangingflies)

Siphonaptera (fleas)

Amphiesmenoptera

Trichoptera (caddisflies)

Lepidoptera (butterflies and moths)

(Mecopterida)
(Holometabola)

More recent molecular analyses find a different arrangement within Holometabola, with Hymenoptera as the earliest branching group.[5]
