Rotting fruit, sap flows on trees, and even bird droppings. The favorite foods of the Red Admiral, Vanessa atalanta. If the Red Admiral can’t find these it will sip flower nectar from Common Milkweed, Red Clover, Aster, and Alfalfa and more.
The dropping Persimmons here on my mountain have been a bigtime draw for these beautiful butterflies, and Coma and Question Mark butterflies. Try putting out some extra ripe fruits to see if some of these butterflies will come by for a visit.
