DART-TOF mass spectral heat maps, Kernel discriminant analysis (KDA) and hierarchical clustering analysis results derived from the DART-TOF mass spectra of hexane extracts of puparial cases of C. rufifacies, L. sericata, L. Cuprina, and C. macellaria and M. domestica.

Panel a: DART-TOF mass spectra rendered as heat maps; Panel b: Kernel discriminant analysis (KDA) was based on 10 feature values. Five principal components accounted for 96% of the variance. The LOOCV was 100%. Panel c: hierarchical clustering analysis dendrogram created from mass spectral heat map data, showing species classifications of the analyzed puparial cases.
