Genus- and species-level comparison of the average Raman spectra obtained for Amblyomma (four species; blue), Rhipicephalus (Boophilus) (two species; black), Rhipicephalus sanguineus sensu stricto (orange), Dermacentor (three species; yellow), Haemaphysalis longicornis (purple), Ixodes scapularis (green), and Haematobia irritans (gray dashed line). Raman vibrational frequency bands known to be associated with blood (red) and guanine (black)
