Although butterfly distributions are known to be positively correlated with the number of larval hostplants used it is not known to what extent larval hostplant number uniquely influences butterfly distributions and to what extent effects are indirect through other variables. This issue is central to understanding the part generalism and specialism in host use play in organism persistence and conservation. Here, we have modelled the links between larval hostplant number and butterfly… Expand

Specialism for larval and adult consumer resources among British butterflies: Implications for conservation
TLDR
It is suggested that habitat fragmentation and regional extinctions are exacerbating resource (nectar and host plant) specialism in British butterflies, and site-specific data obtained according to strict survey protocols are required for determining ecological relationships and to direct site management. Expand
Butterfly Larval Host Plant use in a Tropical Urban Context: Life History Associations, Herbivory, and Landscape Factors
TLDR
Differences arising from the development of a butterfly resource database have important implications for conserving butterfly species within the city area as population size is not simply dependent on host plant abundance. Expand
The importance of resources in determining butterfly population abundance at multiple scales
TLDR
The results suggest that many UK butterfly species are limited at small scales by the availability of hostplants in warm microclimates, but at large scales by dispersal limitation and climatic tolerance. Expand
Butterfly abundance is determined by food availability and is mediated by species traits
TLDR
The determinants of abundance among 1111 populations of butterflies in the UK are explored, spanning 27 species on 54 sites, and strong positive correlations between butterfly abundance and the availability of food resources are found. Expand
The relationship between geographic range size and life history traits: is biogeographic history uncovered? A test using the Iberian butterflies
TLDR
Bivariate correlations between range size and body size, migratory habits or egg size primarily reflected taxonomic patterning and reciprocal correlations with larval diet breadth and adult phenology, and aspects of niche breadth emerged as the most influential determinants of range size. Expand
Butterflies in Portuguese ‘montados’: relationships between climate, land use and life-history traits
Butterfly life-history features are expected to co-vary along environmental gradients related to changes in the vegetation structure or composition; however the direction and intensity should varyExpand
How do low dispersal species establish large range sizes? The case of the water beetle Graphoderus bilineatus
TLDR
The data suggest that a broad habitat niche can prevent landscape elements from becoming barriers for species like G. bilineatus and similar philopatric species, and question the usefulness of site protection as conservation measures for such species. Expand
Optimising trait and source selection for explaining occurrence and abundance changes: A case study using British butterflies
TLDR
It is concluded that analyses of distribution and abundance changes that rely on traits are highly dependent on trait source and trait type, and traits that are based on measures of biotope occupancy should be avoided in explaining changes of abundance and distribution. Expand
Seasonal Patterns of Host Plant Use in an Assemblage of Heliconiini Butterflies (Lepidoptera: Nymphalidae) in a Neotropical forest.
TLDR
Investigation of the influence of seasonal variation on patterns of host plant use (Passifloraceae) by Heliconiini butterflies (Nymphalidae: Helicon iinae) at a Neotropical site in Southeastern Brazil highlights the plasticity boundaries in Heliconuini and possible limiting factors. Expand
Resource grain scales mobility and adult morphology in butterflies
TLDR
The most striking point was the clear relation between the index of relative investment in mobility versus fecundity in females with the spatial dimension of adult feeding resource, which suggests that females might invest more in fecundities when nectar resources are widespread. Expand

Coincidence in the distributions of butterflies and their foodplants
TLDR
A complex relationship between the distribution of butterflies and that of their resources (foodplants) is revealed, and individual polyphagous butterfly species tend disproportionately to be found in areas containing larger numbers of their host plant species. Expand
Flower preferences of woodland butterflies in the UK: nectaring specialists are species of conservation concern
TLDR
A key finding is that many specialist flower users are butterfly species of conservation concern listed in Biodiversity Action Plans, suggesting that management of woodland sites for butterfly conservation should give as much consideration to nectar sources as to host plant sources. Expand
Ecological dynamics of extinct species in empty habitat networks. 2. The role of host plant dynamics
TLDR
Simulated metapopulations of C. minimus in the empty network revealed that time to extinction and patch occupancy were significantly influenced by carrying capacity, butterfly mean dispersal distance and environmental stochasticity, although for most reasonable parameter values, the model system persisted. Expand
Density–distribution relationships in British butterflies. II. An assessment of mechanisms
TLDR
The most conclusive evidence was that statistical patterns of distribution underpinned the positive density–distribution relationship seen amongst the more mobile butterflies, and the results provided evidence against the metapopulation dynamic explanation. Expand
An Ecological Classification of British Butterflies: Ecological Attributes and Biotope Occupancy
TLDR
British butterflies are classified using 136 non-biotope associated binary state ecological attributes describing all stages of butterfly life-cycles to identify species groupings that could serve to predict the response of species groups to environmental change on the basis of their ecological attributes. Expand
Ecological correlates of island incidence and geographical range among British butterflies
The incidence of butterflies on British islands and their geographical (latitudinal) ranges are regressed on ecological and life history variables. The objective has been to investigate theExpand
Identifying rarity in insects: the importance of host plant range
TLDR
Identifying a host plant range below which insect herbivores are therefore rare provides an economical and objective method for producing a shortlist of phytophagous insect species rare enough to warrant conservation measures. Expand
The influence of shade on butterfly numbers in Woodland Rides, with special reference to the wood white Leptidea sinapis
TLDR
Overall, a far greater number of species occurred in the least shaded rides and only a few species actually preferred heavily shaded conditions, suggesting the importance of ride management to the conservation of butterflies in woodland habitats. Expand
Mechanisms of Local Persistence in Coupled Host-Parasitoid Associations: The Case Model of Maculinea rebeli and Ichneumon eumerus
TLDR
This work explores how parasitoid searching intensity and behaviour, and host refuges from parasitism affect the dynamics of the host-parasitoid couple, and links these results to the more general problem of what inferences can be drawn concerning the association between population-level variation in the distribution of parasitism and the population dynamics ofthe system.
