A moth’s wings do much more than help these pollinating insects fly. A team of scientists in Germany initially suspected that moth wings may be able to detect certain aromas based on earlier research. To begin their study, the team gently clipped the edges of the moth’s wings and sprayed them with a gold mist. They placed cut out wings between two electrodes and recorded how they responded to different odor molecules. Both of the malodorous molecules fit neatly into two of the candidates, confirming that the wings have a sense of smell.
