Parasitoids of European butterflies
Parasitoids are insects (mainly Hymenoptera and Diptera) whose larvae develop by feeding on the bodies of other arthropods (mainly immature insects) and the adults are free living. They are of immense importance in practically all terrestrial ecosystems because of their impact on the population levels of their hosts. In contrast to the considerable attention paid to European butterflies their p...
متن کاملClimatic warming increases voltinism in European butterflies and moths.
Climate change is altering geographical ranges, population dynamics and phenologies of many organisms. For ectotherms, increased ambient temperatures frequently have direct consequences for metabolic rates, activity patterns and developmental rates. Consequently, in many insect species both an earlier beginning and prolongation of seasonal duration occurred in parallel with recent global warmin...
متن کاملIntimidating butterflies.
Many butterfly species feature two or four conspicuously coloured eyespots on their wings; the most commonly heard explanation for these markings is that they are used to intimidate predators. However, this explanation has stood, until recently, on the flimsiest of empirical foundations. Now, Adrian Vallin and colleagues have demonstrated empirically the effectiveness of these signals in dissua...
متن کاملSimilarity and specialization of the larval versus adult diet of European butterflies and moths.
Many herbivorous insects feed on plant tissues as larvae but use other resources as adults. Adult nectar feeding is an important component of the diet of many adult herbivores, but few studies have compared adult and larval feeding for broad groups of insects. We compiled a data set of larval host use and adult nectar sources for 995 butterfly and moth species (Lepidoptera) in central Europe. U...
متن کاملMigrating to butterflies
Many of the stories that have appeared in this column recount the way in which the timely appearance of a paper catalyzed the pursuit of a new line of research. The experience is, happily, not limited to new papers. One of the greatest pleasures in research is to discover (or more accurately, to rediscover) a gem of a paper that has been in the literature for some time but whose findings or pro...
