Kleptopharmacophagy

Act of stealing chemical compounds for consumption

Kleptopharmacophagy is a term used for describing the ecological relationship between two different organisms, where the first is stealing the second's chemical compounds and consuming them. This scientific term was proposed by Australian, Singaporean, and American biologists in September 2021 in an article that was published in the journal Ecology by the Ecological Society of America. The phenomenon was first noticed in milkweed butterflies that were attacking caterpillars and drinking their internal liquid, proposedly to obtain toxic alkaloids used for defense, as well as for mating purposes.
