Optimal concentrations in nectar feeding
WebOptimal concentrations in nectar feeding WebMar 1, 2015 · From the formula of nectar intake mass listed above, we can speculate that if all of the hairs erect vertically, namely α ( x )=90°, the proboscis will ideally lift the largest amount of nectar, which can be calculated as . However, the average erection angle was 37.26°, which was not in accordance with the optimal erection angles.
