2- Rhopalosomatidae(Rhopalosomatid Wasps)
- Vespidae(Hornets)
is a superfamily of in the order Hymenoptera. It encompasses a diverse array of wasps exhibiting eusocial, social, and solitary lifestyles, with ecological roles ranging from and scavengers to and herbivores. The superfamily has undergone significant taxonomic revision based on molecular ; studies using nuclear genes have revealed that the historical circumscription of Vespoidea was , leading to the elevation of several former vespoid to separate superfamilies. Currently, Vespoidea in the strict sense comprises only Rhopalosomatidae and Vespidae, though broader treatments may include additional families.

Identification
Female vespoid possess 10 flagellomeres in their , while males have 11 flagellomeres—a consistent diagnostic feature across the superfamily. The pronotum extends posteriorly to reach or surpass the tegula (the small plate covering the wing base). is common, with differences in size, coloration, or wing development between sexes. Wing reduction or complete absence occurs in some of one or both sexes. As members of , only females possess a functional stinger, derived from the modified ovipositor.

Distribution
distribution spanning all major biogeographic regions. Specific distributions vary: Vespidae is nearly worldwide; Rhopalosomatidae is more restricted. Historical records document high in regional faunas, such as 73% of Arabian and 33% of Arabian Vespidae species being to the Arabian Peninsula. The superfamily as traditionally defined included now recognized as distinct superfamilies with their own distributions.
Human Relevance
Vespidae (yellowjackets, hornets, paper wasps) are the most significant human-interacting group within , with impacts ranging from agricultural pollination services to public health concerns due to defensive stinging. Some vespids are valued as biocontrol agents of pest insects. The taxonomic instability of Vespoidea has complicated biological research and conservation assessment, with many regional classified as Data Deficient due to insufficient sampling.
