Colour signals and colour vision play a pivotal role in intraspecific communication and
predator–prey interactions. However, the costs of expressing conspicuous sexual signals at …

Background Opsins are light sensitive receptors associated with visual processes. Insects
typically possess opsins that are stimulated by ultraviolet, short and long wavelength (LW) …

Phototransduction is based on opsins that drive distinct types of Gα cascades. Although
nonvisual photosensitivity has long been known in marine bivalves, the underlying …

Vision plays a vital biological role in organisms, which depends on the visual pigment
molecules (opsin plus chromophore). The expansion or reduction of spectral channels in the …

Light traps are widely utilized to monitor and manage insect pest populations. In late 2018,
the fall armyworm (FAW), Spodoptera frugiperda, invaded China through Yunnan Province …

Luciferases identified or engineered so far emit violet, blue, blue-green, green, yellow, red or
near infra-red light. The unique and beautiful bluish-green bioluminescence of fireworms …

A precondition for colour vision is the presence of at least two spectral types of
photoreceptors in the eye. The order Hymenoptera is traditionally divided into the Apocrita …

Bright iridescent colours are widespread in several aquatic and terrestrial animal taxa and
are usually involved in intraspecific communication and/or predator avoidance. Camouflage …

Color is famous for not existing in the external world: our brains create the perception of
color from the spatial and temporal patterns of the wavelength and intensity of light. For an …

Dragonflies are colorful diurnal insects with large compound eyes. Because they visually
recognize conspecific and heterospecific individuals, their body color plays essential roles in …
