Diurnal and nocturnal hawkmoths (Sphingidae, Lepidoptera) have three spectral types of
receptor sensitive to ultraviolet, blue and green light. As avid flower visitors and pollinators …

Diurnal and nocturnal hawkmoths have been shown to use colour vision for flower
discrimination. Here, we present evidence that the nocturnal hawkmoth Deilephila elpenor …

Nectar-feeding animals can use vision and olfaction to find rewarding flowers and different
species may give different weight to the two sensory modalities. We have studied how a …

The ability to see colour at night is known only from a handful of animals. First discovered in
the elephant hawk moth Deilephila elpenor, nocturnal colour vision is now known from two …

Recent studies have shown that certain nocturnal insect and vertebrate species have true
color vision under nocturnal illumination. Thus, their vision is potentially affected by changes …

The diurnal hummingbird hawkmoth Macroglossum stellatarum can learn the achromatic
(intensity-related) and the chromatic (wavelength-related) aspect of a spectral colour. Free …

Hymenopterans have long been shown to choose colours by means of the spectral
distribution and independently of the intensity (true colour vision). The same ability has only …

Abstract The European hummingbird hawkmoth Macroglossum stellatarum is a diurnal
nectar forager like the honeybee, and we expect similarities in their sensory ecology. Using …

The diurnal hawkmoth Macroglossum stellatarum is known to feed from a variety of flower
species of almost all colours, forms and sizes. A newly eclosed imago, however, has to find …

ERG S (λ) were determined in darkadapted intact preparations of 6 North American firefly
