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

Jumping kinematics in the wandering spider Cupiennius salei
Journal of Comparative Physiology A, 2010Spiders use hemolymph pressure to extend their legs. This mechanism should be challenged when required to rapidly generate forces during jumping, particularly in large spiders. However, effective use of leg muscles could facilitate rapid jumping. To quantify the contributions of different legs and leg joints, we investigated jumping kinematics by high ...

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.

Visual Attention in Jumping Spiders
2019The different ways that animals extract and analyze visual information from their environment is of interest to sensory ecologists. Jumping spiders, well-known for visually guided mating and hunting behavior, are an interesting model for the study of visual attention because they quickly and efficiently integrate information from eight eyes with a ...

Place avoidance learning and memory in a jumping spider
Animal Cognition, 2016Using 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,

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

Dynamic Jump Motion Control of a Jumping Spider Robot with Redundant Degrees of Freedom
ACM Cloud and Autonomic Computing Conference, 2019Aiming at the disadvantages of the traditional jumping robot, such as single jumping form and low movement efficiency, a hexapod robot based on jumping spider is constructed, which can realize multi-direction jumping.

Jumping spider phylogeny (Araneae : Salticidae)
Invertebrate Systematics, 2003A phylogenetic analysis of five sequenced genes (28S, 16S, EF1-α, CO1, ND1) from 81 genera of jumping spiders (Salticidae) and five outgroups supports the monophyly of the Dendryphantinae and Euophryinae and refines the concepts of the Plexippinae and Pelleninae.

JUMPING SPIDERS IDENTIFY VICTIMS BY THEIR ANTENNAE
Journal of Experimental Biology, 2012![][1] Evarcha culicivora jumping spiders are picky eaters by any standards. Explaining that the arachnid's environment is swamped with insects, Ximena Nelson from the University of Canterbury, New Zealand, says, ‘You can see from the diet when you find them in the field that ...
