J Exp Biol (2021) 224 (17): jeb242780.
Published: 13 September 2021
...Elisabeth Adam; Bill S. Hansson; Markus Knaden ABSTRACT Insect pollinators, such as the tobacco hawkmoth Manduca sexta , are known for locating flowers and learning floral odors by using their antennae. A recent study revealed, however, that the tobacco hawkmoth additionally possesses olfactory...

... feeding behavior of crepuscular hawkmoths Manduca sexta , which use their long, actively controlled, proboscis to expertly explore flower-like surfaces. Using machine vision and 3D-printed artificial flower-like feeders, we revealed a novel behavior that shows moths actively probe surfaces, sweeping...

Published: 5 July 2019
... described control strategies to navigate enclosed environments are also used by insects with a different optical system, flight kinematics and phylogenetic background. We tested the role of lateral visual cues for forward flight control in the hummingbird hawkmoth Macroglossum stellatarum (Sphingidae...

...Anna Balkenius; Marie Dacke SUMMARY Here, we analyse the flight behaviour of the hawkmoth Manduca sexta while it approaches three different artificial flower stimuli: a clearly visible blue flower, an invisible scented flower and a flower that is both visible and scented. By tracking the moths...

...Joaquín Goyret; Poppy M. Markwell; Robert A. Raguso SUMMARY Within an appetitive context, Manduca sexta , a nectivorous nocturnal hawkmoth, can be attracted by a range of stimuli including floral volatiles and visual display, carbon dioxide and water vapor. Several studies on this and other flower...

...Jordanna D. H. Sprayberry; Thomas L. Daniel SUMMARY As hovering feeders, hawkmoths cope with flower motions by tracking those motions to maintain contact with the nectary. This study examined the tracking, feeding and energetic performance of Manduca sexta feeding from flowers moving at varied...

Published: 1 September 2004
...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...

Published: 1 June 2002
...James R. Usherwood; Charles P. Ellington SUMMARY Recent work on flapping hawkmoth models has demonstrated the importance of a spiral `leading-edge vortex' created by dynamic stall, and maintained by some aspect of spanwise flow, for creating the lift required during flight. This study uses...
