The foremost expert on Sri Lankan dragonflies and damselflies is not a Sri Lankan. He is a Slovenian named Matjaž Bedjanič who had studied these insects for his PhD. I regularly correspond with him to supply data and to get the IDs confirmed of the dragonflies and damselflies that I photograph in the field. One of these photographed by me in Sinharaja rain forest, turned out to be a new species and is awaiting formal description!
My garden has over 20 species of them; some quite colourful. Shown here are three photographs of one of those garden delights; the extremely beautiful Elusive Adjutant aka Black-headed Basker (Aethriamanta brevipennis), which is listed as a highly scarce resident. This is found regularly in my garden and is quite photogenic.
