The Glasswing Butterfly is one of the rarest and most fascinating insects in the world. This butterfly has transparent wings that resemble crystal glass, making it appear invisible while flying.<br /><br />Scientific name: Greta oto<br /><br />Habitat: It lives in the tropical forests of Central and South America, especially in Costa Rica and Panama.<br /><br />Size: Its wingspan ranges from 5.5 to 6 cm.<br /><br />Why are its wings transparent?<br /><br />The wings of the glasswing butterfly contain a unique composition of proteins and chitin, and lack the colorful scales that most other butterflies have. Instead, the surface of the wings is covered with an irregular nanostructure that prevents light reflection, making it appear completely transparent. This feature gives it the perfect camouflage feature, as it becomes almost invisible to predators while flying or when standing on flowers.<br /><br />Its feeding and reproductive behavior<br /><br />It feeds on flower nectar, especially those containing alkaline compounds that help it defend itself.<br />They avoid predators thanks to their transparent camouflage, but they also have the ability to absorb toxins from plants, making them unpalatable to food.<br /><br />Female butterflies lay their eggs on the leaves of plants that provide food for the larvae after hatching.<br /><br />The importance of glass butterflies in nature<br /><br />They help pollinate plants by moving between flowers.<br /><br />They inspire scientists to develop new optical technologies, such as anti-reflective coatings used in screens and solar cells.<br /><br />Future University is the first university in Iraq
