The host plants of butterflies are plants where the larvae and adults get the food, essential nutrients and the protection. Although the adults are more generalist, but otherwise the larval stage are specific to their host plants generally. Therefore, the host plants will greatly determine the existence of the butterfly species. Based on host plant’s role, this study was focused to identify host plants of butterflies in young secondary forest of Mulawarman Education Forest, host plant’s role to butterflies and butterfly preferences to their host plants.
