Insect Wing Venation Diagram - Entomology Reference Guide #1380032 (License: Personal Use)

This black-and-white line drawing depicts the venation pattern of a typical insect wing, with 18 numbered points marking critical vein junctions and termini. Thick lines represent strong longitudinal veins (e.g., Costa, Subcosta, Radius), while thinner lines indicate cross-veins and branches essential for structural integrity and flight mechanics. The diagram serves as a standard reference for morphological analysis in entomological taxonomy.

Used in academic entomology resources, species identification keys, and biology textbooks; supports user intent to learn or verify wing vein nomenclature for classification, research, or education.
