Most fairyflies possess wings with long bristles (marginal setae) on the fringes. The forewings usually have hypochaeta. These are small bristles (setae) which point distinctly backwards on the ventral surface of the wing membrane. [14] Fairyflies exhibit considerable variation in their wing shapes in comparison to other chalcidoids.

They are thought to represent the lower size limit for endotherm flight. [citation needed] The smallest flying invertebrate is a fairyfly wasp species, Kikiki huna, at 0.15 mm (0.0059 in) (150 μm). [23] Fastest. The fastest of all known flying animals is the peregrine falcon, which when diving travels at 300 kilometres per hour (190 mph) or ...
The wings are moved by the rapid muscular contraction and expansion of the thorax. [11] The wings arise from the meso- and meta-thoracic segments and are similar in size in the basal groups. In more derived groups, the meso-thoracic wings are larger with more powerful musculature at their bases and more rigid vein structures on the costal edge. [7]
Wing structure and colouration often vary with morphs, such as in the aphids, migratory phases of locusts and polymorphic butterflies. At rest, the wings may be held flat, or folded a number of times along specific patterns; most typically, it is the hindwings which are folded, but in a few groups such as the vespid wasps, it is the forewings.
The new species is sexually dimorphic, so males and females differ in “wing size, shape and pattern.” The male specimen was a mostly gray and white with a “few yellowish-brown scales ...
Anaphes nitens is a species of fairyfly, a chalcid wasp in the family Mymaridae. Native to Australia, it is an egg parasitoid of the gum tree snout beetle ( Gonipterus platensis ), a pest of Eucalyptus trees, and has been used in biological pest control of that species.
Pelagornis sandersi comparison with the Andean condor (Vultur gryphus) and the wandering albatross (Diomeda exulans). The sole specimen of P. sandersi has a wingspan estimated between approximately 6.06 and 7.38 m (19.9 and 24.2 ft), [9] giving it the largest wingspan of any flying bird yet discovered, twice that of the wandering albatross, which has the largest wingspan of any extant bird (up ...
