Fig. 12. Log body mass-specific metabolic rate during normal (P_met,norm; open symbols) and maximal hovering flight (P_met,max; filled symbols) vs log body mass (M_b) for Xylocopa varipuncta females. Model II regression: log P_met,norm=2.483–0.883(log M_b), r₂₂=–0.53, P<0.02 (broken line); log P_met,max=2.556–1.216(log M_b), r₂₂=–0.64, P<0.001 (solid line).
