Jordan Lake, 04/30/2021. It was very windy at the lake. This male eastern tiger swallowtail is puddling. The males sip the salts and minerals from the moist sands – sometimes where there are bird droppings and sometimes where there is simply enough standing / puddled moisture to allow the butterflies to sip. The salts and minerals help the male to be more successful in his reproductive activities. The wind would knock the swallowtail off the puddle but he would quickly circle back for another sip. Sometimes you will see several of these butterflies getting their nutrients all in a group.
