Puddling

Butterflies
Mud-puddling is the phenomenon mostly seen in butterflies and involves their aggregation on substrates like wet soil, dung and carrion to obtain nutrients such as salts and amino acids.

Typically, mud-puddling behavior takes place on wet soil. But even sweat on human skin may be attractive to butterflies.More unusual sources include blood and tears.

This behaviour is restricted to males in many species, and in some like Battus philenor the presence of an assembly of butterflies on the ground acts as a stimulus to join the presumptive mud-puddling flock.[4]
