摘　　要：Plant–Lepidoptera interactions are often studied using the pollination or herbivore networks only.Lepidoptera species are involved in two types of plant–insect interactions because they are herbivores as larvae and pollinators as adults.The study of entangled networks is critical,since the interaction of different networks can affect the overall network and community stability.Here,we studied the interaction of plants and Lepidoptera on the Yongxing Island,South China Sea.A plant–lepidopteran pollination network and a plant–lepidopteran herbivore network were built by using data from flower–pollinator and leaf–herbivore interactions.We then combined the two networks into a single network.We measured plant composition similarity within each sub-network and across sub-networks for Lepidoptera species.Our findings indicate that the plant–Lepidoptera pollination network and the herbivory network share significant proportions of Lepidoptera but small proportions of plant assemblages.The pollination network had higher nestedness and connectance than the herbivore network.Agrius convolvuli was the most specialized species,while Zizina otis had the highest species strength in the pollination network.Most Lepidoptera species were highly specialized in the herbivore network and their importance positively correlated across the two networks.Furthermore,there was no dietary composition similarity between the two networks for most Lepidoptera species.Our findings highlight the visible structural difference between the pollination and the herbivore networks.Adult Lepidoptera selects different plants for oviposition and feeding,a strategy that may benefit their reproduction and survival by sustaining adequate resources for their two life stages and the diversity of both plants and insects in oceanic island communities.
