When I was first interested in Odonata, I often took photos of odonates and compared it with other photos from Internet. Diplacodes trivialis is one of odonates I photograph. Comparing with internet photos confused me a lot because the photos didn't tell me what actual size they are. I identified D. trivialis as Orthetrum sabina (because, at that time, I'd never seen O. sabina before). Few weeks later, I saw real O. sabina and I knew what I identified was D. trivialis! that's my "eureka moment".
