Comparison of scorpion behavioral responses to UV under sunset and nighttime irradiances
- Biology
- 2014
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
- BiologyJournal of Arachnology
- 2018
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.
Test of the prey-attraction hypothesis for the scorpion fluorescence
- Biology
- 2020
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.

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

Although the results do not identify a mechanism, fluorescence may function to deter or avoid predation and highlights a potentially fruitful area of future research on predator–prey relations.
Exocuticular hyaline layer of sea scorpions and horseshoe crabs suggests cuticular fluorescence is plesiomorphic in chelicerates
- Biology, Environmental Science
- 2017
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.
Optical properties of a scorpion (Centruroides limpidus)
- Physics
- 2016
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…
Spectroscopic parameters of the cuticle and ethanol extracts of the fluorescent cave isopod Mesoniscus graniger (Isopoda, Oniscidea)
- ChemistryZooKeys
- 2015
The results showed that the autofluorescence observed from living individuals may be due to some β-carboline or coumarin derivatives, some crosslinking structures, dityrosine, or due to other compounds showing similar excitation-emission characteristics.

Ultraviolet light detection: a function of scorpion fluorescence
- Biology, Physics
- 2010
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

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
- Environmental ScienceJournal of Experimental Biology
- 2006
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
- BiologyScience
- 2007
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
- Biology, MedicineCell and Tissue Research

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.

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.
