Figure 2

A–C, proboscis tip equipped with various sensilla types (bas, sensilla basiconica; sty, sensilla styloconica; tri, sensilla trichodea): A, Euselasia aurantia (short-tongued). B, Sarota gyas (short-tongued). C, Eurybia lycisca (long-tongued). D, E, F, G, morphology of sensilla styloconica in these three species (sp, sensory peg; st, stylus).
