A representative image of a D. biarmipes male wing showing two different regions (spotted: S and unspotted: US) used for the Raman spectral analysis. The Raman spectral analysis was done for the both the spotted and the unspotted wing regions. From both the regions two squares were cut and placed under Raman PLC for further analysis
