These shots of a male Indigo Dropwing were taken in Kandy. I found it flying around near the swimming pool and noticed that it kept settling in the same place at the edge of the water. It allowed me to get quite close to photograph it but I was limited by the 1.4 meter minimum focusing distance of the lens. More images and info inside.
The Indigo Dropwing (Trithemis festiva) is an Asian species which is found near flowing water. They are frequently seen on rocks or on vegetation near water ways guarding their territory. Mature males are entirely dark overlaid with a fine whitish pruinescence. Young males look similar to females sporting extensive yellow patches on their abdomen. Females have dark patches at the wing tips and lack the amber spot at the base of their hind wings.
The Indigo Dropwing is often mistaken with the Restless Demon (Indothemis limbata) because both of them are dark blue in colour and they are both similar in size. The orange streaks on the abdomen distinguish it from the Restless Demon which also has dark wing tips.
All the images on this post were taken with a Canon 7D body and the 100-400mm lens. It's a good lens for macro work but the only drawback is the nearest focusing distance of 1.4 meters.
