| Abstract | This investigation was carried out on the Absheron Peninsula, Azerbaijan. The study site was located near the village Gala. This is an open area of ephemeral semidesert covered with the dwarf shrubs, Artemisia fragrans Willd., and Alhagi pseudoalhagi (M.B.), and short grasses and herbaceous plants, predominantly Calendula persica C.A.M., Senecio vernalis Willd. & Kar., Medicago denticulata Willd., Erodium cicutarium (L.), Pterotheca marschalliana (Rchb.), Poa bulbosa L., Anisanthea rubens (L.) and Aegilops biuncialis Vis. A row of wooden electricity poles crossed the study area and M. taeniatus was found only on these poles. Two surveys were conducted in 1998 (30 October and 6 November) and twelve in 1999 (from 13 April to 5 November), which took a total of 23.5 h. All surveys were carried out in daylight, between 11:00 and 17:00. During the surveys, poles were thoroughly searched for M. taeniatus, and the mouthparts of each individual found were inspected with a hand-lens (×4 magnification) to avoid overlooking small prey. Spiders with prey in their chelicerae were captured with a transparent cup, placed in separate vials containing 75% ethyl alcohol, and brought back to the laboratory where the prey was identified and the body lengths of both spider and prey measured. Spiders without prey were left in the field. At the same time, all spiders were classified as either: (1) adult males, which could be easily distinguished by their bicoloured (black and grey) palps (all other individuals of M. taeniatus have grey palps); (2) small juveniles, i.e., spiders less than 5 mm in length; or (3) large juveniles and females, specimens larger than 5 mm, with grey chelicerae. At each survey the numbers of spiders with and without prey were recorded separately for each of these categories. |
