Group of Caleta roxus noliteia puddling on the wet ground, Xuan Son N.P., July 2014
This cute lycaenid is most often spotted and photographed when puddling at muddy forest paths and sandy streambanks
The underside is white with an angled sub-basal band on the forewing which probably gave the butterfly its common name. There is a series of conjoined post-discal black spots on both wings
