From: Wing shape allometry and aerodynamics in calopterygid damselflies: a comparative approach
Relationship between wing shape, expressed as the non-dimensional radius of the second moment of wing area (RSM), and body length (based on the data of Serrano-Meneses et al. [32]for Odonata) (dark circles: non-calopterygid damselflies; triangles: calopterygid damselflies; white circles: dragonflies). Pictures show an example of hindwings of a non-calopterygid damselfly (Lestes viridis), a calopterygid damselfly (Calopteryx maculata) and a dragonfly (Anax imperator).
