Some develop wings but shed them after they are no longer useful. Other groups of insects may have castes with wings and castes without, such as ants . Ants have alate queens and males during the mating season and wingless workers, which allows for smaller workers and more populous colonies than comparable winged wasp species.
At these high speeds, wings are necessary for balance and serving as a parachute apparatus to help the bird slow down. Wings are hypothesized to have played a role in sexual selection in early ancestral ratites and were thus maintained. This can be seen today in both the rheas and ostriches.
Soaring: gliding in rising or otherwise moving air that requires specific physiological and morphological adaptations that can sustain the animal aloft without flapping its wings. The rising air is due to thermals, ridge lift or other meteorological features. Under the right conditions, soaring creates a gain of altitude without expending energy.
This is a list of soaring birds, which are birds that can maintain flight without wing flapping, using rising air currents. Many gliding birds are able to "lock" their extended wings by means of a specialized tendon. [1] Bird of prey.

These genetic mutations may have different results such as the development of muscles that cannot support flight or even result in the lack of wings entirely. [2] Flightless fly models have been especially useful for the study of human neuromuscular diseases such as spinal muscular atrophy, spinobulbar muscular atrophy, myotonic dystrophy ...
8= single pair of wings and 9= halteres Crane fly haltere Halteres of a fly moving. Halteres (/ h æ l ˈ t ɪər iː z /; singular halter or haltere) (from Ancient Greek: ἁλτῆρες, hand-held weights to give an impetus in leaping) are a pair of small club-shaped organs on the body of two orders of flying insects that provide information about body rotations during flight.

The long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the tail or wings of a bird; those on the tail are called rectrices (singular: rectrix), while those on the wings are called remiges (singular: remex). Based on their location, remiges are subdivided into primaries, secondaries and tertiaries. [219] foot ...
