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 Hymenoptera 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 but more recent molecular analyses find a different arrangement within Holometabola, with Hymenoptera as the earliest branching group.^[3]
