Significance Dietary specialization determines an organism’s resource base as well as impacts on host or prey species. There are important basic and applied reasons to ask why some animals have narrow diets and others are more generalized, and if different regions of the Earth support more specialized interactions. We investigated site-specific host records for more than 7,500 species of insect herbivores. Although host specialists predominate, the proportion of specialists is affected by the… 

Quantifying diet breadth through ordination of host association.

An index of host range based on observed associations between plants and insects, and the calculation of multivariate distances among plants in ordination space is proposed, finding that host use is clustered in multivariate space with respect to associations observed across all of the butterfly taxa.

The generality of cryptic dietary niche differences in diverse large-herbivore assemblages.

Ecological niche differences are necessary for stable species coexistence but are often difficult to discern. Models of dietary niche differentiation in large mammalian herbivores invoke the quality,

Climate, species richness, and body size drive geographical variation in resource specialization of herbivorous butterflies

Abstract Revealing drivers of variation in resource specialization is a long-standing goal in ecological and evolutionary research. As a general prediction, the degree of resource specialization

Fundamental resource specialization of herbivorous butterflies decreases toward lower latitudes

The findings suggest that fundamental resource specialization may show different latitudinal patterns from the conventional prediction based on knowledge of realized resource specialization, and emphasize the importance of the current climate as a major factor regulating butterfly morphology and fundamental host breadth.

Host interaction mechanisms in herbivorous insects – life cycles, host specialization and speciation

It is concluded that ‘escape and radiate’ co-evolution rests on unrealistic assumptions and empirical evidence favours sequential evolution of plants and herbivore, and the unique life cycles of insect herbivores may sufficiently explain their extreme diversity within the animal kingdom.

Scale insect host ranges are broader in the tropics

Comparative phylogenetic methods are used to test the effect of latitude on host range in scale insects and find that, on average, scale insects that occur in lower latitudes are more polyphagous, at odds with the general pattern of greater host-plant specificity of insects in the tropics.

Why species richness of plants and herbivorous insects do or do not correlate

It is found that generality of insect communities negatively affected the correlation between species richness of plants and insects, but such negative effect was significant only when the insect species richness was related with the number of plant species interacted with some insect species, instead of with that of total plant species.

Nonadaptive Radiation: Pervasive diet specialization by drift in scale insects?

The results indicate the potential for non-adaptive processes to be important to diet-breadth evolution and taxonomic diversification across herbivorous insects.

Evolutionary Ecology of Plant-Herbivore Interaction

The interaction between plants and their herbivores has spurred the evolution of multiple traits in the resource base – the host plants – as well as the evolution and diversification of different

Phylogenetic relatedness of food plants reveals highest insect herbivore specialization at intermediate temperatures along a broad climatic gradient

The composition and richness of herbivore and plant assemblages change along climatic gradients, but knowledge about associated shifts in specialization is scarce and lacks controlling for the



Four ways towards tropical herbivore megadiversity.

This work presents a comprehensive scheme in which tropical herbivore megadiversity can be partitioned into the following components: more host plant species per se, more arthropod species per plant species, higher host specificity of herbivores, or higher species turnover in the tropics than in the temperate zone.

Guild-specific patterns of species richness and host specialization in plant-herbivore food webs from a tropical forest.

A complex, species-rich plant-herbivore food web for lowland rain forest in Papua New Guinea is described, resolving 6818 feeding links between 224 plant species and 1490 herbivore species drawn from 11 distinct feeding guilds.

Herbivore diet breadth mediates the cascading effects of carnivores in food webs

This study develops and finds support for the novel hypothesis that the proportion of dietary specialist species in a plant’s herbivore community predicts the degree of antiherbivore protection birds provide to plants, and concludes that herbivor diet breadth is a key functional trait underlying the trophic effects of carnivores on both herbivores and plants.

Host specificity of Lepidoptera in tropical and temperate forests

It is suggested that greater specialization in tropical faunas is the result of differences in trophic interactions; for example, there are more distinct plant secondary chemical profiles from one tree species to the next in tropical forests than in temperate forests as well as more diverse and chronic pressures from natural enemy communities.

Insects on Plants: Explaining the Paradox of Low Diversity within Specialist Herbivore Guilds

It is shown that herbivore assemblages are enriched with generalists because these are more completely sampled from regional species pools, and the relative species diversity among guilds is thus scale dependent, as the importance of specialized guilds increases with plant diversity.

Predicting tropical insect herbivore abundance from host plant traits and phylogeny

Plant relatedness did not account for much variation in herbivore abundance, but significant effects of exudates and leaf nitrogen content on caterpillar abundance illustrate how conserved traits at one trophic level may influence community-wide patterns at another.

Why Are There So Many Species of Herbivorous Insects in Tropical Rainforests?

Findings suggest that the latitudinal gradient in insect species richness could be a direct function of plant diversity, which increased sevenfold from the authors' temperate to tropical study sites.

Host Specialization in Phytophagous Insects

Investigations of the causes of host specialization in insects could contribute substantially to the understanding of the origin and maintenance of diversity in this group.


The relationship between butterflies and their food plants is investigated, the examination of patterns of interaction between two major groups of organisms with a close and evident ecological relationship, such as plants and herbivores.
