This plant plays host to a variety of insects and butterflies.
 It is the host plant for Hawaii's non-migratory monarch butterflies.
 Calotropis is an example of entomophily pollination (pollination by insects) and pollination is achieved with the help of bees.
In Calotropis, gynostegium is present (formed by the fusion of stigma and androecium).
The pollen are in a structure named pollinia which is attached to a glandular, adhesive disc at the stigmatic angle (translator mechanism).
These sticky discs get attached to the legs of visiting bees that pull out pollinia when a bee moves away.
When such a bee visits another flower, this flower might be pollinated by the pollinium.
