Hidden Diversity Why are there so many species in the tropics? Niche partitioning by highly specialized plant species seems to be the main generator of high diversity. Condon et al. (p. 1240; see the Perspective by Godfray) show that niche partitioning can also be generated by interactions between plant resources and parasites, resulting in hyperdiverse communities. The cryptic diversity of 14 neotropical fly pollinators and 18 of their highly specific wasp parasites induced mortality… Expand
Host shifting and host sharing in a genus of specialist flies diversifying alongside their sunflower hosts
TLDR
It is suggested that rapid and recent adaptive introgression and speciation in this group of plants may have instigated the diversification of their phytophagous fly associates, including the convergence of >1 species onto the same shared host plants. Expand
Host shifting and host sharing in a genus of specialist flies diversifying alongside their sunflower hosts
TLDR
It is suggested that rapid and recent adaptive introgression and speciation in Helianthus may have instigated the diversification of Strauzia, with some flies converging upon a single plant host after their respective ancestral host plants hybridized to form a new sunflower species. Expand
Determinants of parasitoid communities of willow‐galling sawflies: habitat overrides physiology, host plant and space
TLDR
The results indicate that barcode‐ and phylogeny‐based analyses of food webs that span forested vs. tundra or grassland environments could improve the understanding of vertical diversification effects in complex plant–herbivore–parasitoid networks. Expand
Population Structuring and Phylogenetic Inference in a Species of Tropical Fly Using Double Digest Rad Markers
TLDR
Double-digest restrictionassociated sequencing is used to examine population structure and phylogenetic relationships between individuals of Blepharoneura species 10, which uses multiple host plants and parts throughout its range and shows that, although the majority of divergence is linked to geographic location, host use may also contribute to differentiation. Expand
Genetic differentiation associated with host plants and geography among six widespread species of South American Blepharoneura fruit flies (Tephritidae)
Tropical herbivorous insects are astonishingly diverse, and many are highly host‐specific. Much evidence suggests that herbivorous insect diversity is a function of host plant diversity; yet, theExpand
Tree phylogenetic diversity promotes host–parasitoid interactions
TLDR
This study indicates that host–parasitoid interactions in species-rich forests are related to the PD of the tree community, which influences parasitism rates through parasitoid abundance, and shows that effects of tree community PD are much stronger than effects ofTree species richness, can cascade to high trophic levels, and promote trophics interactions.

Diversity, host ranges, and potential drivers of speciation among the inquiline enemies of oak gall wasps
TLDR
It is clear that the North American Synergus have experienced several transitions among gall hosts and tree habitats and that host-use is correlated with reproductive isolation, though it remains too early to tell whether shifts to new hosts are the initiators of speciation events in Synergy inquilines of oak gall wasps, or if host shifts occur after reproductive isolation has already evolved. Expand
Anatomy of a Neotropical insect radiation
TLDR
It is suggested that most lineage origins occur in allopatry, usually without shifts in host-use, and that subsequent dispersal results in assembly of communities composed of multiple sympatric non-interbreeding populations of flies that share the same hosts. Expand
Patterns of temporal and enemy niche use by a community of leaf cone moths (Caloptilia) coexisting on maples (Acer) as revealed by metabarcoding
TLDR
It appears that niche partitioning is not necessary for closely related herbivores to stably coexist on shared hosts, and co-occurrence without resource partitioning may provide an additional axis along which herbivorous insects attain increased species richness. Expand

Cascading host-associated genetic differentiation in parasitoids of phytophagous insects
TLDR
The results suggest that cascading HAD could play an important role in the diversification of parasitoids attacking phytophagous insects, and the existence of cryptic host-associated lineages also suggests that the diversity of Parasitoids may be vastly underestimated. Expand
Host specificity of Lepidoptera in tropical and temperate forests
TLDR
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. Expand
Why Are There So Many Species of Herbivorous Insects in Tropical Rainforests?
TLDR
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. Expand
Sequential Sympatric Speciation Across Trophic Levels
TLDR
It is reported that the parasitic wasp Diachasma alloeum has formed new incipient species as a result of specializing on diversifying fly hosts, including the recently derived apple-infesting race of R. pomonella. Expand
Extreme diversity of tropical parasitoid wasps exposed by iterative integration of natural history, DNA barcoding, morphology, and collections
TLDR
DNA barcoded 2,597 parasitoid wasps belonging to 6 microgastrine braconid genera reared from parapatric tropical dry forest, cloud forest, and rain forest in northwestern Costa Rica and combined these data with records of caterpillar hosts and morphological analyses to result in a much more fine-scaled understanding of Parasitoid diversity and host specificity.

Hidden Neotropical Diversity: Greater Than the Sum of Its Parts
TLDR
It is suggested that neotropical herbivorous insect diversity is not simply a function of plant taxonomic and architectural diversity, but also reflects the geographic distribution of hosts and the age and area of the neotropics. Expand
Geographic Patterns in the Evolution of Resistance and Virulence in Drosophila and Its Parasitoids
TLDR
It is found no evidence for genotype‐specific virulence and defense, which makes “Red Queen”–type coevolution unlikely, and the most important explanation for the patterns is geographic differences in host‐parasitoid community structure. Expand
The tri-trophic niche concept and adaptive radiation of phytophagous insects
TLDR
It is argued that bi- and tri-trophic niche concepts have different implications for understanding herbivore community structure, population divergence, and evolutionary diversification of phytophagous insects. Expand
BUTTERFLIES AND PLANTS: A STUDY IN COEVOLUTION
TLDR
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. Expand
Unprecedented ichneumonid parasitoid wasp diversity in tropical forests
TLDR
It is shown with primary data that the species richness of Ichneumonidae is markedly underestimated in tropical areas and that latitudinal diversity patterns in the family remain uncharacterized, and the true extent of tropical orthocentrine diversity is revealed. Expand
