... the effect of wing damage on the manoeuvrability of hummingbird hawkmoths ( Macroglossum stellatarum ) tracking a motorised flower. This assay allowed us to sample a range of movements at different temporal frequencies, and thus assess whether wing damage affected faster or slower flight manoeuvres. We show...

... thresholds have been determined in two species only: the honeybee ( Apis mellifera ) and the butterfly Papilio xuthus . Here, we present the wavelength discrimination thresholds (Δλ) for the hawkmoth Macroglossum stellatarum . We compared the data with those found for the honeybee, the butterfly P. xuthus...

...Anna Balkenius; Almut Kelber SUMMARY Diurnal and nocturnal hawkmoths have been shown to use colour vision for flower discrimination. Here, we present evidence that the nocturnal hawkmoth Deilephila elpenor and the diurnal hawkmoth Macroglossum stellatarum also have colour constancy. Colour...

...Eric Warrant; Klaus Bartsch; Claudia Günther ABSTRACT The fast-flying day-active hawkmoth Macroglossum stellatarum (Lepidoptera: Sphingidae) has a remarkable refracting superposition eye that departs radically from the classical principles of Exnerian superposition optics. Unlike its classical...

...Almut Kelber ABSTRACT 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 its first flower by means of an innate flower template. This study investigates which visual...

...Almut Kelber ABSTRACT Newly eclosed specimens of the day-active hawkmoth Macroglossum stellatarum were trained to artificial flowers in dual-colour choice situations. Learning curves were obtained from learning and reversed-learning experiments. Initially, learning behaviour was influenced...
