Towards a functional resource-based concept for habitat: a butterfly biology viewpoint
It is argued that a resource-based concept is critical for butterfly conservation and call for the development of a resource database on butterfly biology.
Habitats and Resources: The Need for a Resource-based Definition to Conserve Butterflies
Current definitions of habitat are closely allied to the concept of patch and matrix. This concept is, for instance, central to the prevailing metapopulation models of population dynamics. But,…

Contemporary geography dominates butterfly diversity gradients within the Aegean archipelago (Lepidoptera: Papilionoidea, Hesperioidea)
Aim We compare the influence of contemporary geography and historical influences on butterfly diversity for islands in the Aegean archipelago.
Distance sampling and the challenge of monitoring butterfly populations
The standard ‘Pollard Walk’ methodology employed by the UKBMS is critically evaluated, finding that it is not viable as a wholesale replacement for simpler methods for large-scale monitoring of multispecies butterfly communities by volunteer recorders.
Patch occupancy in Coenonympha tullia (Muller, 1764) (Lepidoptera: Satyrinae): habitat quality matters as much as patch size and isolation
Patch occupancy by Coenonympha tullia has been surveyed in 166 sites in Northumberland, UK and it was found in 117 of them and absent in 37, suggesting that there is potential for predicting changes in occupancy of sites from site specific data in the face of changes to biotopes.
The influence of temperature on migration of Lepidoptera into Britain
A unique 113‐year record of numbers of nine migrating butterflies and 20 migrating moths is examined in relation to temperatures on the migration route, to temperatures in England, and to the North…
Bias in Butterfly Distribution Maps: The Effects of Sampling Effort
Data from the Greater Manchester Butterfly Atlas (UK) reveal a highly significant and substantial impact of visits on both species' richness and species' incidence in squares. This effect has been…

Abstract. 1. To determine whether rarity and decline is linked to organism ecology, associations have been examined between butterfly larval host‐plant competitive, stress‐tolerant, ruderal (C‐S‐R)…
