Dragonfly Wings

Wing venation is a defining feature of genus.

Some specifics of wing venation can be critical in differentiating between certain congeners (species within the same genus). For example, one classic case within Europe lies in separating Keeled Skimmers (Orthetrum coerulescens) and Southern Skimmers (Orthetrum brunneum) where the so-called Rspl (Radial Supplemental Vein) comes into play.

Here is a diagram of dragonfly wings with several occasionally mentioned features indicated.
