Fig. 2.

Cuticular hydrocarbon (CHC) profiles of the 12 Myrmica species. Chromatograms were aligned to each other using the n- alkanes. A simple cladogram of the 12 species is shown on the left to demonstrate genetic relatedness (based on Jansen et al. 2010). Observe how the chain lengths of the profiles shift with M. sabuleti and M. scabrinodis at the lower end (C₂₃-C₂₉), and M. ruginodis and M. schencki at the higher end (C₂₇-C₃₉), in addition to the different compounds represented by different peaks. CHC profiles shown are from Spanish populations other than M. lobicornis which is from Finland
