In Figwe show range of venation patterns seen in wings, with sparse venation in Diptera at one end, and the dense venation in Odonata at the other end Venation is therefore, undeniably a key factor of species-specific functional traits of the wings; however, the mechanism underlying wing vein formation among insects largely remains unexplored. In this study, we address the relationship between venation pattern and wing flexibility by measuring the flexural stiffness of wings (in both the spanwise and chordwise directions) and quantifying wing venation ininsect species from six orders Wing venation patterns are highly diverse, with some wings partitioned into just a few “domains” (vein-bounded regions) and others into many thousands. Our knowledge of the genetic basis of wing development is solely restricted to Drosophila melanogaster The vein pattern in insect wings allows this lightweight structure to carry multiple biological functions. Here, an investigation of the angular distribution of the vein struts in dragonfly wing venation remains unknown, and measurements of the mechanical properties of wings are rare. In Figwe show range of venation From a physical perspective, insect wings are slender quasi two-dimensional membranes criss-crossed by a network of tubular veins. Insect wings are also dynamic living structures composed of stiff tubular veins, which supply hemolymph to veins containing trachea and nerves The patterns formed by veins can partition The vein pattern in insect wings allows this lightweight structure to carry multiple biological functions. Here, an investigation of the angular distribution of the vein struts in dragonflyClustering a network into communities quantifies a third major trait of a wing: a topological measure of the complexity of venation patterns. Venation is therefore, undeniably a key factor of species-specific functional traits of the wings; however, the mechanism underlying wing vein formation among insects largely venation of an insect wing is as follows: Costa– unbranched, Subcosta– two branched, Radius– unbramched, Radius sector– four branches, Medius anterior– two branches, Clustering a network into communities quantifies a third major trait of a wing: a topological measure of the complexity of venation patterns.
