malformalady:Butterflies puddling in an old tire. Lepidoptera(butterflies and moths) are diverse in their strategies to gather liquid nutrients. Typically, mud-puddling behavior takes place on wet soil. But even sweat on human skin may be attractive to butterflies. This behaviour is restricted to males in many species, and in some, the presence of an assembly of butterflies on the ground acts as a stimulus to join the presumptive mud-puddling flock. -- source link
