Fig. 1. (A) Discriminant analysis of 12 variables (relative proportions of
cuticular hydrocarbons) selected by stepwise discriminant analysis for queens
from four L. humile colonies (CHH, COC, FOR, RTP) used in the queen
adoption assay for which queen cuticular hydrocarbons were extracted with
solvent and (B) discriminant analysis of 13 variables selected by stepwise
discriminant analysis for queens from the same four L. humile
colonies for which queen cuticular hydrocarbons were sampled using a
non-destructive method. + marks the centroid of each group.
