Our FGASA field guides tell us dragonfly wings are typically held at right angles to their bodies, whilst damselfly wings are typically held parallel to the abdomen, whilst the mayfly and wisp are daintier. We recommend getting books (A guide to the dragonflies and damselflies of South Africa ) and papers ( https://www.sanbi.org/wp-content/uploads/2018/04/sanbibiodiveristyseries21.pdf ) about these beautiful flying creatures.
