Differences between laboratory and field-derived spectra. a Principal components analysis showing the difference between scores calculated for PC-1 (which explains 88% of the variation) and PC-2 (8% of the variation) for laboratory (blue; square) and field-derived (red; circle) mosquitoes. b Loading plot from PCA showing that water bands at 1450 nm and 1930 nm accounted for 88% of the total variance observed. R denotes reflectance c difference between undried (dashed line) and dried (solid line) mosquito spectra. In b and c blue horizontal lines indicate peaks associated with water
