The forewing of an insect is the uppermost wing which covers and protects the hindwing. It is an important feature for identification of different insect species. The term "forewing" is specific to insects, but there are other words that can be used as synonyms for it. Some alternatives include the anterior wing, the top wing, or the front wing. These terms help to describe the position and function of this important aspect of insect anatomy. Insects with developed forewings are able to fly long distances and with great agility, making this feature crucial to their survival and success.
