Throughout evolutionary history, insects have evolved modified wings that can provide articulation and membrane. However, for 200 million years, their genes were unable to inhibit the formation of wings. However, those genes were eventually lost, although they still prevent insect development. During this time, wing-like structures have evolved into an important feature for insects: camouflage.
In order to survive, animals must have the ability to recover their wings if they are damaged. Damage to wing tissue affects their shape, size, and structural integrity, affecting flight performance and overall fitness. Many vertebrates can recover from damage to their wings by exploiting general mechanisms of tissue repair. Birds and bats, for example, can replace lost feathers through moulting. Insects, on the other hand, must rely on behavioural mechanisms to compensate for damage.
Many insect experts believe that flies can regenerate their wings. However, this is a rare occurrence. This is because most flies have two pairs of wings, whereas most other winged insects have four. Most flies are attracted to moist organic materials, which is why they are sometimes called “filth flies.” These flies are not only important scavengers, but they are also highly dangerous for humans.
Flies regenerate their wings after damage by changing their wingstroke frequency and amplitude. This is done by regulating the firing rate of indirect flight muscle motor neurons. This helps the flies maintain their moment equilibrium and maintain their weight support.
