...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...
