Hymenopterida is a superorder of insects, comprising Hymenoptera and the orders of Panorpida (Mecoptera, Siphonaptera, Diptera, Trichoptera and Lepidoptera).[1] The superorder is a member of Endopterygota and most closely related to the orders of Neuropterida and Coleopterida (Coleoptera and Strepsiptera).
The cladogram based on a 2008 DNA and protein analysis, shows the internal relationships of the superorder as a clade of Hymenoptera and the orders of Panorpida. [2][3][4][5]
