Sycophaginae is a group of non-pollinating fig wasps considered closely related to the fig pollinators (Agaoninae, Tetrapusiinae, and Kradibiinae) in the most recent phylogenetic analyses. They occur in all tropical regions and are associated with Ficus subgenera...

Background. The ‘whirling’ defensive behavior of Pholcus ancoralis (L. Koch, 1865) was studied in a forest and laboratory in Mo’orea, French Polynesia. This behavior involves fast web-borne gyration to dissuade predators and is widespread in the Pholcidae family....

Background Functional traits are the primary biotic component driving organism influence on ecosystem functions; in consequence, traits are widely used in ecological research. However, most animal trait-based studies use easy-to-measure characteristics of species...
