Scorpions are largely solitary, nocturnal arachnids that glow a bright cyan-green under UV light. The function of this fluorescence is a mystery. Previous studies of four species from three families have shown that scorpion lateral and medial eyes are maximally sensitive to green light (around 500 nm) and secondarily to UV (350–400 nm). Scorpions are negatively phototactic, and we used this behaviour to assay the responses of desert grassland scorpions, Paruroctonus utahensis, to 395 nm UV…

Comparison of scorpion behavioral responses to UV under sunset and nighttime irradiances
TLDR
This study tested the responses of desert grassland scorpions to 395 nm UV light at irradiances corresponding to an hour before sunset, and resulted in several methodological refinements, including automated tracking of the subjects' movements that should prove useful in future behavioral studies of scorpion phototactic behavior.
New, sensitive behavioral assay shows scorpions are attracted to multiple wavelengths of light
TLDR
This new assay is more sensitive than previous assays for detecting scorpion photoresponse and will be useful for future studies, suggesting that the photoreceptors may respond to a broad spectrum of light or that thePhotoreceptor population may not be as homogeneous as previously thought.
Ultraviolet fluorescence discovered in New World flying squirrels (Glaucomys)
TLDR
Fluorescence in varying intensities of pink was observed in females and males of all extant species of Glaucomys, the New World flying squirrels across all sampled geographic areas in North and Central America and a temporal range of 130 years.
Test of the prey-attraction hypothesis for the scorpion fluorescence
TLDR
Whether the fluorescence of the scorpion Centruroides granosus Thorell, 1876 lures the house cricket Acheta domesticus Linnaeus, 1758 is investigated and crickets were on average closer to male scorpion in the outdoor arena and closer to female scorpions in the laboratory arenas, in line with the results of the arena experiment.
Fluorescence in scorpions under UV light; can chaerilids be a possible exception?
TLDR
It is suggested here that, in at least some species of the family Chaerilidae Simon, this phenomenon is absent, and this new discovery may initiate important comparative eco-physiological studies.
Characterization of the fluorescence intensity and color tonality in the exoskeleton of scorpions.
TLDR
The properties of emission from the scorpion's exoskeleton are studied by means of digitally processed photographs taken of living specimens under ultraviolet illumination and complemented with standard spectroscopic measurements of emission and excitation spectra, suggesting that fluorescence may correlate directly to the ecomorphotype of the scorpions.
Bright green fluorescence of Asian paper wasp nests
An exceptionally bright fluorescent biomatter was discovered when exploring, with UV-A light, the nests of several oriental paper wasp species of the genus Polistes, a genus of diurnal social
Reduced avian predation on an ultraviolet-fluorescing caterpillar model
Abstract Many caterpillars exhibit patterns of ultraviolet (UV) fluorescence, although its purpose is unclear. We used realistic plasticine models of a fluorescing caterpillar species, the Polyphemus
Optical properties of a scorpion (Centruroides limpidus)
Scorpions, elusive by nature, tend to appear nocturnally and are usually not appreciated when encountered. The exoskeleton is capable of fluorescing allowing for their detection at night in order to
Exocuticular hyaline layer of sea scorpions and horseshoe crabs suggests cuticular fluorescence is plesiomorphic in chelicerates
TLDR
The presence of a hyaline layer in horseshoe crabs and sea scorpions suggests that several putative functions for cuticular UV fluorescence in scorpions can be discounted and may be plesiomorphic among chelicerates.

Light wavelength biases of scorpions
TLDR
It is concluded that different wavelengths of light affect scorpion locomotory behaviour differently, and animals moved sporadically and significantly faster under green light compared to IR light treatments.
Ultraviolet light detection: a function of scorpion fluorescence
TLDR
Evidence is interpreted as evidence that fluorescence aids in the detection of and response to ultraviolet light, and possible implications of this result in natural habitats are discussed.
Reducing scorpion fluorescence via prolonged exposure to ultraviolet light
TLDR
This technique potentially opens up new options for testing a variety of hypotheses about possible functions of scorpion fluorescence including potential effects on cuticle strength, visual responses, predation, cannibalism, and mating.
Crepuscular and nocturnal illumination and its effects on color perception by the nocturnal hawkmoth Deilephila elpenor
TLDR
The addition of von Kries color constancy significantly reduced the effect of changing illuminants on chromatic contrast, suggesting that, even in this light-limited environment, the ability of color vision to provide reliable signals under changing illumnants may offset the concurrent threefold decrease in sensitivity and spatial resolution.
Sex-Specific UV and Fluorescence Signals in Jumping Spiders
TLDR
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.
The lateral eyes of the scorpion, Androctonus australis
TLDR
The construction of the dioptric apparatus as well as the anatomy of the retina imply that in the lateral eyes of Androctonus australis visual acuity is reduced, however, a certain degree of spatial discrimination may be retained by the presence of a relatively high number of arhabdomeric cells.
A Metasomatic Neural Photoreceptor in the Scorpion
TLDR
The telsonic nerves, although sensitive to light, are not solely responsible for the extraocular perception of light, and cutting of the telsic nerves does not abolish the response in any of the species of Heterometrus used.
A light response in the tail of Urodacus, a scorpion.
TLDR
The part played by the eyes in the light-dependent behaviour of the scorpion was investigated and the spectral sensitivity of this light response was determined.

TLDR
The response of the scorpion Leiurus quinquestriatus to different stimuli and its general sensory physiology have been investigated and it was found to react positively to humidity and negatively to light and to temperatures above 39 °C.

TLDR
A comparison of the fluorescence spectra between genders across two sympatric species of scorpions was conducted and no difference between genders was found, but a statistically significant difference between species was detected.
