Abstract. Color discrimination in jumping spiders Hasarius adansoni was examined by heat-avoidance learning in association with colored papers. The arena for the experiment was divided into two halves by a pair of colored papers. The colored papers used in this study were blue, green, yellow, red, white, gray and black. In training sessions, one half of the arena was heated from the bottom by a hot plate, and freely walking spiders were individually trained to avoid the heated half. In… 

Flexible color learning in an invertebrate predator: Habronattus jumping spiders can learn to prefer or avoid red during foraging

It is suggested that jumping spider color generalization may differ from that of avian predators and such invertebrate predators should be considered more when thinking broadly about the evolution of prey color.

Colouration in crab spiders: substrate choice and prey attraction

Yellow spiders on white flowers were the only pairing where bees rejected spider-occupied flowers, especially in cases where the contrast between the two was relatively strong, and T. spectabilis select flower colours adaptively in a way that deceives honeybees, or at least does not deter them.

Condition dependence of male display coloration in a jumping spider (Habronattus pyrrithrix)

Evidence that green coloration is age dependent and alternatives to indicator models for colorful displays in jumping spiders are discussed and different degrees of condition dependence for male display colors are shown.

Jumping Spiders Associate Food With Color Cues In A T-Maze

This study demonstrates that P. princeps can learn the location of prey by color cues alone, a challenging task, and adds to the growing literature on learning in spiders.

Male ornamental coloration improves courtship success in a jumping spider, but only in the sun

The results suggest that ornamental coloration is not required for mating in H. pyrrithrix, but that red coloration improves success in certain contexts, implications for the evolution of elaborate, multimodal courtship displays by animals that interact in variable environments.

Structurally assisted super black in colourful peacock spiders

It is proposed that this pre-existing, qualitative sensory experience—‘sensory bias’—is also found in spiders, leading to the convergent evolution of super black for mating displays in jumping spiders.

Odor alters color preference in a foraging jumping spider

Giving jumping spiders the choice between red or black prey in either the presence or absence of odor from the chemically defended coreid bug found spiders were more likely to avoid the color red compared with when the odor was absent, and the presence of the odor had no effect on the spiders’ responses to the color green.

Extreme ultraviolet sexual dimorphism in jumping spiders (Araneae: Salticidae)

This is the first full UV characterization of a salticid spider and the first study to demonstrate an extreme sexual UV dimorphism in jumping spiders, and provides evidence that UV reflectance may comprise important sexual signals in jumping spider.

Behavioural evidence of UV sensitivity in jumping spiders (Araneae: Salticidae)

These findings clearly demonstrate that C. umbratica males are capable of seeing UV wavelengths and that UV cues are necessary and sufficient for this species to enable the agonistic displays, and suggest that UV light may have an important role to play in intra-specific communication in jumping spiders.
