Rearing environment affects behaviour of jumping spiders
Animal Behaviour, 2000We tested the effect of rearing conditions on the behaviour of jumping spiders, Phidippus audax. Spiders were assigned randomly to either small or large cages that either were empty or contained a painted dowel. Laboratory-reared spiders were raised from second instar to adult in these environments.

Journal of Experimental Biology, 2000
ABSTRACT Portia fimbriata from Queensland, Australia, is an araneophagic jumping spider (Salticidae) that includes in its predatory strategy a tactic (cryptic stalking) enabling it to prey effectively on a wide range of salticids from other genera. Optical cues used by P.

Firefly flashing and jumping spider predation
Animal Behaviour, 2012Bioluminescent 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

Spectral sensitivities of jumping spider eyes
Journal of Comparative Physiology ? A, 1976Spectral sensitivities of the anterior lateral, posterior lateral and anterior median eyes of the jumping spider,Menemerus confusus Boes. et Str. have been studied by recording electroretinograms (ERGs) and receptor potentials. The anterior and posterior lateral eyes have a single type of visual cell with a maximum spectral sensitivity at about 535–540

Visual attention and processing in jumping spiders
Trends in NeurosciencesJumping 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.

Spatial abilities in jumping spiders.
2020Cognition refers to any state of information processing, including memory, perception, decision-making, and learning. Decision-making, the main component of this thesis, is a cognitive process that allows animals to evaluate their environment so as to avoid less favourable situations.

The Jumping Mechanism of Salticid Spiders
Journal of Experimental Biology, 1959ABSTRACT 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

The jumping spiders of Mozambique (Araneae: Salticidae)
ZootaxaOnly 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.

Fine structure of the eyes of jumping spiders
Journal of Ultrastructure Research, 1971The 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 ...
