摘要

The natural prey of the jumping spider Salticus tricinctus (C. L. Koch, 1846) was studied in Absheron Peninsula, Azerbaijan. The percentage of specimens of S. tricinctus found while feeding was low (7.6%), reflecting the short duration of the observations as well as low frequency of feeding. Investigation has shown that S. tricinctus is a polyphagous predator feeding on a wide range of arthropods. Representatives of six arthropod orders were found in its diet. The primary food of S. tricinctus was Diptera, which accounted for 70.3% of total prey. The length of prey killed by S. tricinctus ranged between 1.0 and 9.0 mm (mean 3.4 mm) and constituted from 22.2 to 200.0% (mean 77.2%) of the length of their captors. The most frequently captured prey were arthropods not exceeding the length of the spiders (72.4%).
