The larger butterfly and the one on the right is Pea blue Lampides boeticus. While the rest are all Zebra blue Leptotes plinius. The blues sit on wet soil as well as wet stone. Once I saw a stone little bigger than a coconut completely covered by blues. Line blues, plains cupid, zebra blue, pea blue, dark cerulean, common cerulean, guava blue all of them can be seen on soil.
