      • Tansy aphid metapopulations are not only structured by dispersal limitations and population growth but also by the biotic community in which they live.
      • Mutualistic ants shape the metapopulation structure of tansy aphids by increasing the colonisation success of empty plant patches.
      • Top-down predation effects do not exclusively drive aphid metapopulation structuring in this system, it is rather a combination of many factors acting at the same time.

      • Organisms are subjected to multiple stressors in natural situations; however, the impacts of combined stressors on fitness are rarely assessed.
      • Here we show that the combination of food limitation and phylloplane bacteria had negative synergistic effects on survival, growth rate and pupal mass, but feeding on induced foliage had mixed effects.
      • Fecundity was only reduced by food limitation but insects fed damaged leaves produced smaller eggs.

      • Nearly all pollinator taxa (honey bees, wasps, other Hymenoptera and non-bombyliid flies) spent less time foraging on the predator cluster.
      • Visiting honey bees and wasps avoided inflorescences within 90 mm of the crab spider: they spent three- and 18-fold more time, respectively, foraging on more distant flower clusters.
      • Whether honey bees can smell spiders was then tested, and this study provides the first demonstration that honey bees will avoid crab spider odour alone at a food source.

      • Increasing the intensity of intraspecific competition lowers the host selectivity threshold in a density-dependent way.
      • Increasing the density of conspecifics increases the orientation to sub-optimal hosts' odours in a linear fashion.
      • Modulation of the orientation to sub-optimal host odours is a general response to every sub-optimal host.

      • The adaptive causes of symbiont transmission strategies are little understood. Here we studied the vertical transmission of ectosymbiotic mites living on bird feathers.
      • We found that feather mites transmit massively from parents to chicks even though adult birds are considered to be safer hosts.
      • We compared the observed transmission patterns with hypothetical predictions and concluded that massive transmission could be interpreted as a way to reduce intraspecific competition or to spread the risk of host mortality.

      Version of Record online: 2 MAY 2017 | DOI: 10.1111/een.12413

      • We found a male polymorphism in Sepsis thoracica, which is largely determined by condition-dependent plasticity rather than genes.
      • The males' polymorphism involves a trade-off between body size and immunity.
      • Contrary to the predictions of the density-dependent prophylaxis hypothesis, larval density did not affect the immune system activity of the individuals.

      • When fully grown, butterfly larvae enter a wandering phase and typically pupate at a distance from their host plant, probably because mortality from predation decreases with distance from the host.
      • The duration of the wandering phase is probably a trade-off between mortality during wandering and mortality during the pupal period, giving more weight to reducing pupal mortality in overwintering generations.
      • In accordance with theory, we show that larvae wander for longer in diapausing, overwintering, generations compared with directly developing, summer, generations of the bivoltine European swallowtail butterfly, Papilio machaon.
