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).Weaver J.S.I.

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.
