Leatherywinged

Leatherywinged refers to a characteristic found in certain insects, most notably bats and some moth species. This descriptive term pertains to the texture and appearance of their wings, which are not feathered like those of birds nor membranous like those of dragonflies. Instead, leathery wings are typically composed of a tough, somewhat flexible membrane stretched over a framework of bone or chitin.

In bats, these leathery wings are formed from a patagium, a specialized membrane of skin that extends from the elongated fingers, along the sides of the body, to the hind limbs and tail. This membrane allows for agile and controlled flight. The texture is often described as smooth but resilient, capable of withstanding the rigors of aerial movement.

Some species of moths also exhibit leathery wing characteristics, though it is less pronounced than in bats. These moths may have wings that are thicker and less translucent than other lepidopterans, giving them a more robust or leathery feel. This can be an adaptation for protection or for camouflage against certain backgrounds. The term "leatherywinged" is therefore a morphological descriptor used to categorize and understand the physical traits of these flying creatures.
