![]() ![]() One position postulated insect wings evolved from pre-existing structures, while the second proposed insect wings were entirely novel formations. During the 19th century, the question of insect wing evolution originally rested on two main positions. The evolutionary origin of the insect wing is debated. 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. ![]() ![]() Wing structure and colouration often vary with morphs, such as in the aphids, migratory phases of locusts and polymorphic butterflies. In some cases, wings are produced only at particular times in the life cycle, such as in the dispersal phase of aphids. Rarely, the female is winged but the male not, as in fig wasps. The wings are present in only one sex (often the male) in some groups such as velvet ants and Strepsiptera, or are selectively lost in "workers" of social insects such as ants and termites. Those insects with indirect flight have muscles that attach to and deform the thorax, causing the wings to move as well. In insects with direct flight, the wing muscles directly attach to the wing base, so that a small downward movement of the wing base lifts the wing itself upward. Physically, some insects move their flight muscles directly, others indirectly. The patterns resulting from the fusion and cross-connection of the wing veins are often diagnostic for different evolutionary lineages and can be used for identification to the family or even genus level in many orders of insects. The wings are strengthened by a number of longitudinal veins, which often have cross-connections that form closed "cells" in the membrane (extreme examples include the dragonflies and lacewings). They are found on the second and third thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few insects lack hindwings, even rudiments.
