Social parasitism in ants has fascinated naturalists for more than 200 years. The life strategies of these species take many forms, but one of the most unusual and iconic is undoubtedly the Anergates atratulus (Schenck, 1852). This social parasite has completely lost the worker caste and has thus become an extreme inquiline. Females bear degenerate...

Using seventeen-year records of daily light trap catches of predatory Neuroptera (Chrysopidae, 13 species) and Coleoptera (Coccinellidae, 10 species), and of phytophagous Lepidoptera (Noctuidae, 79 species) we tested a hypothesis predicting that the range of annual fluctuations of catch size is greater in aphidophages, whose diet occurs irregularly...
