The second picture shows the Great Mormon butterfly/Papilio memnon flying close to the ground. Although I have seen this magnificent butterfly many times, this is my first attempt at capturing it. Sadly, not a close shot. My book of butterflies says that the females of the species are seen near flowers and food plants whereas males are usually seen mud-puddling.
The last picture was taken in my backyard. I was cleaning this area and had poured a bucket of water. Just then this beautiful swallowtail landed to quench its thirst. It remained for a few minutes and gave me enough time to take some pictures!
The Common Bluebottle/Graphium sarpedon is said to prefer wetter, wooded regions. They are avid mud-puddlers and are seen in large groups in damp patches. Google has several such images.They are found in South and South-east Asia as well as Australia where they are also called the Blue Triangle butterflies.
