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