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.
A more detailed analysis of the problem shows that the work done by the wings is converted primarily into kinetic energy of the air that is accelerated by the downward stroke of the wings. The power is the amount of work done in 1 s; in the insect used as an example, makes 110 downward strokes per second.
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]
This has led to a common misconception that bees "violate aerodynamic theory". In fact it merely confirms that bees do not engage in fixed-wing flight, and that their flight is explained by other mechanics, such as those used by helicopters. [62] In 1996 it was shown that vortices created by many insects' wings helped to provide lift. [63]
Young females rarely leave the nest and guard the entrance while the older females work, resulting in unworn wings and mandibles in the younger females. [2] Additionally, X. virginica is the only known species in which one-year-old females cohabit the nest with two-year-old females that do all the labor.
Examples of frenulo-retinacular wing coupling in male and female moths Other groups of moth have a frenulum on the hindwing that hooks under a retinaculum on the forewing. [ 4 ] The retinaculum is a hook or tuft on the underside of the forewing of some moths .

Drones die off or are ejected from the hive by the worker bees in late autumn, dying from exposure and the inability to protect or feed themselves, and do not reappear in the bee hive until late spring. The worker bees evict them as the drones would deplete the hive's resources too quickly if they were allowed to stay. [3]
