How oniscophagous spiders overcome woodlouse armour
Original language description
Woodlice (Isopoda: Oniscoidea) are well defended by a heavy armour and many species have noxious secretions. Oniscophagy (feeding on woodlice) may be an important part of the biology of at least some members of the spider genus Dysdera (Dysderidae). Yetthere little is known about the diet and possible specializations for feeding on woodlice in these spiders. Dysdera has unusual variability in mouthpart morphology, which may be related to the diet. Here, we investigate five species of Dysdera and consider the relationship between mouthpart morphology, capture frequency and prey-capture behaviour. We show that species with unmodified chelicerae readily capture a variety of arthropods, but refuse woodlice as prey, whereas species with modified cheliceraefeed on woodlice and reject most of the other prey. Among the oniscophagic species, the grasping methods used during the capture of woodlice varied. Species with elongate chelicerae inserted one chelicera into the soft ventral side of th
