A portrait of a zebra spider which catched a black bean aphid (Aphis fabae). The picture has been made with magnification factor 5 and f/13, using a Canon 7D and the Canon macrolens MP-E 65mm/f2.8..The zebra spider, Salticus scenicus, is a common household jumping spider. Like other jumping spiders, it does not build a web. It uses its four pairs of large eyes to locate prey and its jumping ability to pounce and capture it. Zebra spiders are often noted for their 'curiosity' when observed by humans; many seem aware of their audience and seem to respond to observation by raising their heads and studying the observer...Female zebra spiders are 5–7 millimetres long and males are 5–6 mm . The most distinctive feature of these spiders is their two very large eyes, which is typical for jumping spiders. Although they have eight eyes, the two at the front are the largest and give them excellent binocular vision. These tiny spiders are black with white hairs that form stripes...Aphis fabae is a true bug in the order Hemiptera. Common names include blackfly, black bean aphid, bean aphid and beet leaf aphid. It is a widely distributed pest of agricultural crops (source: Wikipedia).
