Biphasic activity of a jumping spider

Die Naturwissenschaften, 2010
Individual variation is a ubiquitous and important factor that affects ecological dynamics. This study examined individual variation in the nest-use pattern of the jumping spider Phidippus audax. Although the jumping spider is a diurnal species, field observations in this study revealed that the majority of individuals remained in their nests during ...

Predatory Behavior of Jumping Spiders

Annual Review of Entomology, 1996
Salticids, the largest family of spiders, have unique eyes, acute vision, and elaborate vision-mediated predatory behavior, which is more pronounced than in any other spider group. Diverse predatory strategies have evolved, including araneophagy, aggressive mimicry, myrmicophagy, and prey-specific prey-catching behavior. Salticids are also distinctive

Fine structure of the eyes of jumping spiders

Journal of Ultrastructure Research, 1971
The four pairs of eyes in two species of jumping spiders (Metaphidippus harfordi and Phidippus johnsoni) were studied by light and electron microscopy. Unique features of the anteromedial eyes, used in acute vision, are: stratification of receptors (basis of color vision?); rhabdomeres in anterior row of receptors in two planes perpendicular to each ...

Prolonged milk provisioning in a jumping spider

Science, 2018
Spider nursery Mammals produce milk to feed their offspring, and maternal care often continues well after the young can forage for themselves. Though other cases of milk-like secretions have been found, this combination of ongoing maternal care has largely been considered a uniquely mammalian trait. Chen et al.

Hypersensitivity in the Anterior Median Eye of A Jumping Spider

Journal of Experimental Biology, 1976
ABSTRACT Changes in sensitivity of the photoreceptor cells of the anterior median eye of the jumping spider Menemerus confusus Boes, et Str. have been studied by recording electroretinograms (ERGs) and receptor potentials. The amplitudes of the responses (ERGs and receptor potentials) increase during repetitive stimulation, with a ...

Visual attention and processing in jumping spiders

Trends in Neurosciences
Jumping spiders have extraordinary vision. Using multiple, specialized eyes, these spiders selectively gather and integrate disparate streams of information about motion, color, and spatial detail. The saccadic movements of a forward-facing pair of eyes allow spiders to inspect their surroundings and identify objects.

The Jumping Mechanism of Salticid Spiders

Journal of Experimental Biology, 1959
ABSTRACT Photographs of the jumping spider Sitticus pubescens (Salticidae) show that the jump is almost entirely due to the sudden straightening of the fourth pair of legs. Multiple-image photographs show the importance of a silk drag-line in controlling the jump. The torques at the leg joints have been estimated. Extension torques occur

Firefly flashing and jumping spider predation

Animal Behaviour, 2012
Bioluminescent flashing in fireflies, while primarily a sexual signal, is known to deter some predators while attracting others. We tested whether flashing serves an antipredator function against two species of diurnal, visually hunting jumping spiders, Phidippus princeps and Phidippus audax. To confirm anecdotal reports that fireflies flash during the

The jumping spiders of Mozambique (Araneae: Salticidae)

Zootaxa
Only 26 species of jumping spiders have been recorded from Mozambique to date. The present study is based on materials from four museum collections. Fourteen species are described as new to science: Habrocestum mozambicum sp. nov. (♂ ♀), Hyllus bisulcus sp. nov. (♂), H. ornatus sp. nov. (♂ ♀), H. simplex sp. nov. (♂), H. tetensis sp.

Place avoidance learning and memory in a jumping spider

Animal Cognition, 2016
Using a conditioned passive place avoidance paradigm, we investigated the relative importance of three experimental parameters on learning and memory in a salticid, Servaea incana. Spiders encountered an aversive electric shock stimulus paired with one side of a two-sided arena. Our three parameters were the ecological relevance of the visual stimulus,
