摘要: The expectation that the niche breadth of species in relatively unpredictable environments should be greater than comparable more reliable is violated by larval feeding habits temperate zone Macrolepidoptera. Species feed primarily on herbaceous plants are often restricted to a single plant family which eat leaves trees or shrubs. This pattern appears attributable coevolution oviposition preferences with evolution defense systems, probably tend toward diversity floristically diverse communities and uniformity less communities.
