Abstract

We describe the presence and abundance of two orb-weaving spider species of the genus Argiope (A. lobata and A. bruennichi) in the island Columbrete Grande (archipelago of Columbretes, Castellón, Spain). The number of observed spiders in a surface of 10m2 was variable and dependant on the presence of vegetation. The density of A. lobata (10m2) was higher (mean = 4.4 spiders, min= 0.5 and max= 17.5) than the density of A. bruennichi (mean = 2.3, min=1, max= 6.6). However, both species did overlap in the same habitat. The current literature (Web of Science-SCI) indicates that there is not available information on the biology and ecology of these two spider species in Spain. We therefore present the results of preliminary observations on the ecology and behaviour of that species. We also discuss the possible origin of the species in the island within the frame of the biogeography of the genus Argiope.
