Volume and rate of fluid deposition during consecutive pad press-downs in Nauphoeta cinerea. (a) Volumes of adhesive fluid deposited at different step frequencies (data show means ± s.e.) (black line, 0.476 Hz (n = 5); grey dashed line, 0.152 Hz (n = 5); grey dotted line, 0.086 Hz (n = 4)). (b) Influx rate Q of adhesive fluid in depleted adhesive pads, for different frequencies of simulated steps (means ±s.e.). (c) Relative fluid loss per step (k) for different step frequencies (means ±s.e.).
