Butterflies Obtain Nutrients From Scat

The males of some species will also drink at muddy puddles or damp earth for mineral salts and on scat or animal carcasses to get amino acids and other vital nutrients. This added nutrition is needed for them to generate spermatophores, the packets of sperm and nutrients that are transferred to the female during mating.

White Admiral Butterflies Puddling

If you’ve been traveling on sunny dirt roads lately, chances are that you have seen White Admiral butterflies all over them. They are in the road to obtain salts and minerals that have leached from the soil into standing puddles and moist dirt. Because butterflies do not have chewing mouthparts as adults, they must drink their meals. While nectar is their main source of nutrition, males often supplement their diet with these minerals. The act of acquiring nutrients in this manner is referred to as “puddling.” If there’s no water around, a butterfly may regurgitate into the soil and then drink in the hope of retrieving minerals. In addition to finding butterflies on dirt roads, look for them puddling on animal scat.
