Sexual selection on jumping spider color pattern: investigation with a new quantitative approach

, 2021
How animals assess information encoded in individual color patches have been extensively studied, yet the role of both individual color patches and gross color pattern (i.e., the combination of color patches) remains understudied.

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 ...

Phylogenetic relationships and systematics of the jumping spider genus Colopsus with the description of eight new species from Sri Lanka (Araneae: Salticidae)

Journal of Natural History, 2020
The Sri Lankan jumping spider species first described as Colopsus cancellatus and its close relatives are an understudied yet charismatic part of the fauna of the island.

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

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 ...

Association and reversal learning abilities in a jumping spider

Behavioural Processes, 2014
The ability to learn and overwrite learned associations allows animals to respond adaptively to changes in their environment. However, such behavioural plasticity is presumed to be costly and the question arises to which extent animals with restricted neuronal capacity are capable of such flexible behaviour.

Bionomics of the Jumping Spider Metaphidippus galathea1,2,3

Annals of the Entomological Society of America, 1972
A laboratory study was conducted on the biology of the spider Metaphidippus galathea (Walckenaer). The study determined longevity, mating behavior, fecundity, incubation and hatching, growth and development, and mortality. Sexual dimorphism is marked in M. galathea .

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.
