Famously, Charles Darwin predicted that there must have been moths with exceedingly long proboscises in Madagascar after he saw the orchids from that island with deeply recessed nectar.
Forty years later, a night - flying subspecies of moth with a nearly foot - long proboscis was found feeding from the flower.
Other work on how this proboscis evolved proposes that early moths started with chewing mouthparts and ate spores and pollen, says Harald W. Krenn of the University of Vienna.
Only when flowers produced volatiles did the moths stay long enough to drink nectar, and only when they stayed long enough did they deliver enough pollen on their proboscis to successfully pollinate other scenting flowers.
This choice test revealed that the moth's proboscis remained much longer in the part of the «flower» that smelled than in the other part.
The researchers showed that floral scent is crucial for successful pollination: Manduca sexta hawk moths, the most important pollinators of the wild tobacco species Nicotiana attenuata, use their proboscis to smell the floral volatiles when they visit flowers.
«Hawk moths have second nose for evaluating flowers: Using olfactory neurons on their proboscis, moths weigh which flowers to visit.»
Apparently, the hawk moth is able to smell floral scent with the tip of its tongue, Haverkamp, one of the first authors of the study, notes this surprising result: «Our study shows that the function of the proboscis is much more complex than was previously thought.
It has a 12 - inch long nectary — there is a tube where the nectar accumulates — and he predicts that there is a moth, thinks it has to be [a] moth with a very long proboscis basically like a straw that would be, maybe 11 inches long.
A hawk moth (Manduca sexta) uses its eight - centimeter - long proboscis to drink nectar from a flower of Nicotiana alata, a species of wild tobacco also called jasmine or winged tobacco.
They were able to show that Manduca sexta moths acquired the highest energy gain when they visited flowers that matched the length of their proboscis.
«Scent guides hawk moths to the best - fitting flowers: Researchers show that Manduca sexta recognizes scent of flowers matching its proboscis, thereby optimizes energy gain.»
Active olfactory receptor genes on the proboscis Using molecular biology techniques the scientists identified the Manduca sexta genes which were active on the proboscis of the moth.
