TY - JOUR ID - 768529 AU - Řezáč, Milan - Pekár, Stanislav - Lubin, Yael PY - 2008 TI - How oniscophagous spiders overcome woodlouse armour JF - Journal of Zoology VL - 275 IS - 1 SP - 64–71 EP - 64–71 PB - Blackwell Publishing SN - 09528369 KW - Araneae KW - Dysdera KW - diet KW - specialist N2 - 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). Yet there 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 chelicerae feed on woodlice and reject most of the other prey.
