Effect of light and age on phototaxis. 1‐ and 7‐day‐old bees, which have been exposed to light pulses for 1 day, and age‐matched dark‐kept control bees were tested for positive phototaxis at four different relative light intensities. 1d, 1‐day‐old bees; 7d, 7‐day‐old bees; *P‐value < 0.05; **P‐values < 0.01; n.s.: P‐value ≥ 0.05.
