Spiders are powerful predators, but the threats confronting them are numerous. A survey is presented of the many different arthropods which waylay spiders in various ways. Some food-specialists among spiders feed exclusively on spiders. Kleptoparasites are found among spiders as well as among Mecoptera, Diptera, Lepidoptera, and Heteroptera. Predators are found within spiders’ own population (c...

We examined the defaecation behaviour of Argiope aurantia both in natural situations and in a greenhouse. The spiders defaecated more frequently at night than during the day. The nightly pattern of defaecation was not related to time of feeding. A. aurantia displayed at least two distinct behaviours related to defaecation, one of which involved leaving the web. These results are discussed in re...

This checklist records 631 spider species and subspecies belonging to 49 families in Israel. Species distributions are given in both generalised (by main geographic areas of the country) and detailed (by localities) form. Twenty-seven records are considered as doubtful and another ten are based on misidentifications. A historical survey is provided. Each record is presented in its original comb...

We present protocols and conditions for specimen storage, DNA extraction and storage, and the subsequent RAPD (Random Amplified Polymorphic DNA) profiling of spiders . Three common UK species, Lepthyphantes tenuis (Blackwall 1852), Enoplognatha ovata (Clerk 1757) and Clubiona reclusa (Cambridge 1863), members of the Linyphiidae, Theridiidae and Clubionidae respectively, were chosen to serve as ...
