alae的意思|示意

Alae (plural form of ala) are wings of various insects and birds. The word alae derives from the Latin word ala meaning “wing”.

In insects, the alae play an important role in the insect's ability to fly. These wings help to lift the insect and give it the ability to maneuver in the air. The alae can be used for both gliding and flapping. Depending on the type of insect, the alae may be more pronounced or even replaced by other appendages, such as halteres.

In birds, the alae are the large feathers that are located on each side of the wings. They provide the bird with lift during flight and also help to stabilize it in the air. Depending on the type of bird, the alae may be more or less pronounced. In some species of hawks, for example, the alae are elongated feathers that help the bird to fly faster and more efficiently.

In addition to their function in flight, alae can also be used for display and communication. Certain types of birds, such as the peacock, have brightly colored alae that are used to attract the attention of potential mates.

Overall, alae are essential for the flight of birds and insects and also play an important role in social displays.
