Summary1.We report here a psychophysical technique for studying the spectral sensitivity of jumping spiders (family Salticidae), based on a newly discovered oculomotor reflex.2.Our results, obtained fromMaevia inclemens (Salticidae), are compatible with electrophysiological findings of retinal cells maximally sensitive in the green and ultraviolet regions of the spectrum.3.Sensitivity to longer wavelengths (>650 nm) has been controversial. In our study jumping spiders are shown to have a broad… 

Spectral sensitivity of the ctenid spider Cupiennius salei

The spectral sensitivity of adult male Cupiennius salei Keys, a nocturnal hunting spider, was studied in a behavioural test and three visual opsins that correspond to UV and middle to long wavelength sensitive opsins as described for jumping spiders were found.

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.

Optics of the ultraviolet reflecting scales of a jumping spider

It is shown that this configuration produces a second reflectance peak at approximately 385 nm, accounting for the observed reflection in the ultraviolet, providing the spiders with two colour signals, both of which are important in mating displays.

Spectral transmission of the principal-eye corneas of jumping spiders: implications for ultraviolet vision

It is found that the corneas of all measured species were able to transmit UV light, making the perception of UV possible, suggesting that UV perception is widespread in salticids.

Colour blindness of the movement-detecting system of the spider Cupiennius salei

The results indicate that C. salei is not able to discriminate the coloured stimuli from distinct shades of grey, and it is evident that the movement-detecting system in this spider appears to be colour blind.

Sex-Specific UV and Fluorescence Signals in Jumping Spiders

Evidence is provided for this separation in the jumping spider Cosmophasis umbratica, which has UV reflectance and UV-induced green fluorescence restricted to males and females, respectively, which demonstrates the importance of both sex-specific hues as sexual signals for effective intraspecific communication.

Predatory Encounters of Yllenus Arenarius (Araneae, Salticidae) with Flies (Diptera)

Predatory Encounters of Yllenus Arenarius (Araneae, Salticidae) with Flies (Diptera) Predatory behaviour of YLLenus arenarius hunting flies was studied and two modes of approach in close proximity of prey were observed.

Efferent innervation of photoreceptors in spiders

The anterior median (AM) eye of the nocturnal spider Araneus ventricosus showed a marked circadian oscillation of sensitivity, but that of the diurnal spider Menemerus confusus showed no circadian

Spectral sensitivity, absolute threshold, and visual field of two tick species,Hyalomma dromedarii andAmblyomma variegatum

The first demonstration in ticks of spectral and absolute sensitivity by the behavioral approach and of the visual field by ERG is demonstrated, suggesting that tick eyes possess features of both spider eyes and insect ocelli.

Lack of neophobic responses to color in a jumping spider that uses color cues when foraging (Habronattus pyrrithrix)

Testing whether naive lab-raised jumping spiders (Habronattus pyrrithrix) exhibit similar patterns of color neophobia to birds found no evidence that either prey novelty nor color (nor their interaction) had an effect on how quickly prey was attacked.



Spectral sensitivities of jumping spider eyes

Spectral sensitivities of the anterior lateral, posterior lateral and anterior median eyes of the jumping spider have been studied by recording electroretinograms (ERGs) and receptor potentials, suggesting that each receptor layer contains a different photopigment.

Jumping spiders distinguish other jumping spiders from potential prey by the geometry of their legs, and it is suggested that scanning is a pattern-recognition procedure in which the torsional movements are concerned with the spatial alignment of line or edge detectors, and the horizontal component with providing relative motion between these detectors and the stationary stimulus.

Tetrachromatic visual system in the moth Spodoptera exempta (Insecta: Noctuidae)

The retina in the compound eye of the African army-worm moth, Spodoptera exempta, contains four different visual pigments that cause this eye's distinct red sensitivity up to more than 700 nm, found electrophysiologically.

Ultraviolet and green receptors in principal eyes of jumping spiders.

It is concluded that jumping spiders have the potential for dichromatic color vision.

The spectral sensitivities of identified receptors and the function of retinal tiering in the principal eyes of a jumping spider

Summary1.The functional organisation of the central retina of the anterior median (AM) eyes of a jumping spider,Plexippus (Salticidae) is examined by anatomical, electrophysiological and optical

Two theories are offered to account for the retinal layering of jumping spiders: Either the spider uses different layers to examine maximally sharp images of objects at different dis tances; or each layer exploits the sharpest image of distant objects, but for light of different wavelengths.

The neural organization of the first optic ganglion of the principal eyes of jumping spiders (Salticidae)

The first optic ganglion (FOG) of the principal eyes of jumping spider has been studied by both light and electron microscopy and shows the presence of numerous fine post‐terminal processes extending away from the main portion of the retinal terminal.

Spectral Sensitivity and Color Vision in Invertebrates

The visual world offers a variety of information that enables animals to orient themselves to their surroundings. One specific feature of the visual information is the wavelength difference of light
