Retention rate for three ant species dropped into glass vials filled with three types of N. rafflesiana pitcher fluid and pure water (TYP=typical form, highly viscoelastic; EL+=elongate form, moderately viscoelastic; EL– =elongate form, watery; WAT=water, see Materials and methods). Each bar represents 10 ants. Asterisks (*P <0.05) indicate significant differences between pitcher fluids and the control (water).
