The smaller species may have only two or three hamuli on each side, but the largest wasps may have a considerable number, keeping the wings gripped together especially tightly. Hymenopteran wings have relatively few veins compared with many other insects, especially in the smaller species. [13]
Apocrita, wasps in the broad sense, appeared in the Jurassic, and had diversified into many of the extant superfamilies by the Cretaceous; they appear to have evolved from the Symphyta. [4] Fig wasps with modern anatomical features first appeared in the Lower Cretaceous of the Crato Formation in Brazil, some 65 million years before the first ...
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants.Over 150,000 living species of Hymenoptera have been described, [2] [3] in addition to over 2,000 extinct ones. [4]
Chalcidoid wasps are small wasps (most within the range 0.5–5 mm). However the group does include the smallest known insect (Dicopomorpha echmepterygis males have a body length of 0.14–0.24 mm); the largest chalcidoids include Leucospis gigas with a body length of up to 21 mm [2] and Doddifoenus wallacei with a body length of up to 19.6 mm.

The wasps that inhabit a particular tree can be divided into two groups; pollinating and non-pollinating. The pollinating wasps are part of an obligate nursery pollination mutualism with the fig tree, while the non-pollinating wasps feed off the plant without benefiting it. The life cycles of the two groups, however, are similar.
Vespoid wasp females have antennae with 10 flagellomeres, while males have 11 flagellomeres. The edge of the pronotum reaches or passes the tegula. Many species display some level of sexual dimorphism. Most species have fully developed wings, but some have reduced or absent wings in one or both sexes.
They tend to be less conspicuous than the social (wasps) do,” Kimsey said, adding that they are “good to have around” to eat other bugs such as caterpillars. There are roughly 300 species of ...
Fairyflies are some of the most common chalcidoid wasps, but because of their minute sizes they are seldom noticed by humans. This apparent invisibility, their delicate bodies, and their hair-fringed wings have earned them their common name. [2] Fairyflies are found in temperate and tropical regions throughout the world.
