Monarch Butterflies Use Plants As Medicine (Video)

Humans aren’t the only species that finds creative ways to self-medicate, according to a recent study by scientists at Emory University.

Research journal Ecology Letters recently published findings that demonstrate monarch butterflies use certain plants as medication to cure themselves and their offspring of disease.

“We have shown that some species of milkweed, the larva’s food plants, can reduce parasite infection in the monarchs,” said study leader Jaap de Roode, an evolutionary biologist at Emory University (Futurity).

“And we have also found that infected female butterflies prefer to lay their eggs on plants that will make their offspring less sick, suggesting that monarchs have evolved the ability to medicate their offspring.”

During the study, experiments showed that egg-laying monarchs that are infected with a parasite choose plants that have a medicinal benefit for their caterpillars.

Scientists hope that learning more about how wildlife uses plants to prevent disease could lead to a better understanding of how humans can benefit from organic medications as well.

“Studying organisms engaged in self-medication gives us a clue as to what compounds might be worth investigating for their potential as human medicines,” said University of Michigan chemical ecologist Mark Hunter, who collaborated with de Roode’s group on the research.

animals are super smart, many species self medicate with herbs, primates, horses, goats, they are incredible!

Great information. It is interesting that an insect such as a butterfly can actually make a distinction as to what is good for their offspring and we as humans struggle with that! Amazing!

Wow! Perfection is in nature!
