Phänologie und Lebenszyklus von Wolfspinnen (Araneae, Lycosidae) auf Wirtschaftswiesen des Altmühltales/Bayern
Phenology and life cycle of wolf spiders (Araneae: Lycosidae) from meadows of the Altmühl Valley (Bavaria, Southern Germany)
A faunistic study was carried out for two years in the valley of the river Altmühl in 1986 and 1987. With the help of 57 BARBER-traps in meadow habitats near Weissenburg-Gunzenhausen more than 14500 adult and 7700 young wolf spiders were caught. 13 species were found in total: Alopecosa pulverulenta (CLERCK), Arctosa leopardus (SUNDEVALL), Aulonia albimana (WALCKENAER), Pardosa agrestis (WESTRING), Pardosa amentata (CLERCK), Pardosa palustris (LINNE), Pardosa palluta (CLERCK), Pirata hygrophilus THORELL, Pirata latitans (BLACKWALL), Pirata piraticus (CLERCK), Pirata piscatorius (CLERCK), Trochosa ruricola (DE GEER) and Trochosa spinipalpis (F.P.-CAMBRIDGE). The pit-fall traps were installed throughout the year and were controlled every two weeks. The resulting data allow a detailed description of the life cycle of seven species: Alopecosa pulverulenta, Pardosa amentata, Pardosa palustris, Pardosa pullata, Pirata latitans, Pirata piraticus and Trochosa spinipalpis. The life cycle of Alopecosa, Pardosa and Pirata species was found last year. Trochosa species need almost two years to reach maturity.
