Classification
Kingdom Animalia (Animals)
Phylum Arthropoda (Arthropods)
Subphylum Hexapoda (Hexapods)
Class Insecta (Insects)
Order Hymenoptera (Ants, Bees, Wasps and Sawflies)
No Taxon (Aculeata - Ants, Bees and Stinging Wasps)
Superfamily Vespoidea
Family Vespidae
Pronunciation
Typically VESS-pə-dē. In contrast to typical pronunciations, the pronunciation as in Latin instead would be wɛs pɪ dae̯ or wes pɪ dae̯ (wehs pee die or ways pee die).
Synonyms and other taxonomic changes
Polybiinae recently merged with Polistinae, with some of the tribes rearranged
Explanation of Names
Vespidae Latreille 1802
Numbers
~300 spp. in 36 genera in our area; ~5,000 spp. in ~270 genera total(1)
Overview of our fauna (* –taxa not yet in the guide)
Family Vespidae
Subfamily Polistinae Brachygastra · Mischocyttarus · Polistes · Polybia*
Identification
Wings folded longitudinally at rest; first discoidal cell of FW greater than half the wing length
Inner margin of eye usually notched
Pronotum extending back to the tegulae and thus appearing triangular in lateral view and horseshoe-shaped from above
Keys: northeastern spp.(2) • CA spp.(3)
Range
Worldwide
Food
Masarinae are phytophagus (collect pollen and nectar for their young) ▪ Eumeninae & Euparagiinae catch specific prey to provision nests ▪ Polistinae & Vespinae collect various arthropods and carrion for their young
Life Cycle
Eumeninae, Euparagiinae, and Masarinae are solitary; Polistinae and Vespinae, eusocial; Stenogastrinae (Oriental) contains solitary and social forms
Remarks
The social vespids can be distinguished from nonsocial ones by having mandibles with a cutting/chewing surface near apex rather than along the inner margin
