... 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...

... behaviors. We found that activation of one line ( VT041723-GAL4 ) produces ‘proboscis holding’ behavior (extrusion of the mouthpart without withdrawal). Further analysis showed that the proboscis holding phenotype indicates an aversive response, as flies pre-fed with either sucrose or water prior...

...Seung Chul Lee; Bo Heum Kim; Sang Joon Lee The butterfly Pieirs rapae drinks liquid using a long proboscis. A high pressure gradient is induced in the proboscis when cibarial pump muscles contract. However, liquid feeding through the long proboscis poses a disadvantage of high flow resistance...

.... Other members of the CSP family have been reported to perform different functions, from delivery of pheromones to development. This report is focused on a member (CSP4) of the family that is highly and almost exclusively present in the proboscis of two sibling noctuid species, Helicoverpa armigera and H...
