“…The central area of layer 1, the "fovea", is the only region that receives a sharply focused image (Blest et al 1990). Remarkably, the distance between the receptors in the fovea (c. 1 |im) appears to be optimal for resolution given the details of the rest of the optical system.…”

“…Jumping spiders (Salticidae), having large eyes, acute vision, and complex predatory behaviour (Land 1969a, b;Forster 1982;Blest et al 1990;Jackson & Pollard 1996), are commonly envisaged as generalist insectivores (e.g., Foelix 1982), although most species appear to be averse to ants. Yet there is a minority group within this large family that routinely feeds on ants (myrmecophagic species) (Edwards et al 1974;Cutler 1980;Jackson & van Olphenl991, 1992).…”

Siler sp., Euophrys sp. 1 and 2, and six species of Chalcotropis feed on ants in nature. Capture techniques and preferences of each species were studied in the laboratory using a wide variety of ants and other insects. Siler sp. usually attacked ants, but not other insects, from directly behind. Euophrys sp. 1 and 2 consistently attacked ants, but not other insects, head on. Chalcotropis attacked large ants head on, but there was no particular orientation of attacks on small ants or on other prey regardless of size. All species tended to stab ants, but not other prey, several times before holding on. In three types of preypreference tests, each of the nine salticid species took dolichoderine, formicine, myrmicine, ponerine, and pseudomyrmecine ants in preference to a variety of other insects (aphids, bugs, caterpillars, cockroaches, crickets, flies, gnats, lacewings, mantises, may flies, midges, mosquitoes, moths, plant and leafhoppers, Z97045 Received 15 December 1997; accepted 8 April 1998 plant lice, and termites). Testing with laboratoryreared spiders showed that the development of preference for ants and ant-specific prey-capture behaviour did not depend on prior experience with ants. Each species was shown in tests with dead, motionless lures to be capable of distinguishing between ants and other types of prey independent of the different movement patterns of the prey. Findings are discussed in relation to other studies on specialised salticids and in relation to the structure and function of the salticid eye.

“…Movement detected by the PM eyes leads to heightened activity of the AM eye muscles, which can however also be elicited by flickering, non-moving stimuli (Fenk and Schmid 2011). The beautiful optics of the large forward-facing principal, or anterior median (AM), eyes of salticids has been extensively investigated (Eakin and Brandenburger 1971;Blest et al 1990;Land 1969a;Williams and McIntyre 1980), as has their role in visually-guided behaviour (Harland and Jackson 2000). At the expense of a large field of view, this pair of eyes features spatial acuity (form vision) unparalleled among terrestrial invertebrates, and supports colour vision (Williams and McIntyre 1980).…”

“…Salticids are a distinctive exception, because they have unique complex eyes (10)(11)(12) that support spatial resolution (Ϸ0.04°) without parallel in other animals of comparable size (13). For example, the highest acuity known for insects (14) is Ϸ0.4°, and the acuity of the human eye (15) (0.007°) is only about five times better than that of a salticid.…”

Spiders do not feed directly on vertebrate blood, but a small East African jumping spider (Salticidae), Evarcha culicivora, feeds indirectly on vertebrate blood by choosing as preferred prey female mosquitoes that have had recent blood meals. Experiments show that this spider can identify its preferred prey by sight alone and by odor alone. When presented with two types of size-matched motionless lures, E. culicivora consistently chose blood-fed female mosquitoes in preference to nonmosquito prey, male mosquitoes, and sugar-fed female mosquitoes (i.e., females that had not been feeding on blood). When the choice was between mosquitoes of different sizes (both blood-or both sugar-fed), small juveniles chose the smaller prey, whereas adults and larger juveniles chose the larger prey. However, preference for blood took precedence over preference for size (i.e., to get a blood meal, small individuals took prey that were larger than the preferred size, and larger individuals took prey that were smaller than the preferred size). When presented with odor from two prey types, E. culicivora approached the odor from blood-fed female mosquitoes significantly more often the odor of the prey that were not carrying blood.predation ͉ Salticidae ͉ prey choice ͉ behavior
