Eumaeus
Cycadians
Eumaeus is a genus of lycaenid butterflies commonly known as cycadians, characterized by their striking coloration and obligate association with cycad host plants. Members of this genus are specialist herbivores that sequester neurotoxic compounds from their hosts, rendering them chemically defended against predators. Several species have experienced severe population declines due to overharvesting and habitat destruction of their cycad hosts, followed by remarkable recoveries linked to urban ornamental plantings. The genus represents a notable example of reconciliation ecology, where conservation success has been achieved through human-modified landscapes.
