Handling times (Mean, SE, s, inverse-transformed) of male and female E. jugularis at straight artificial flowers (K = 0 inverse mm) measuring 35, 40, 45, and 50 mm in length, with 10 microliters of nectar (M10 = solid circles, F10 = open circles). For both sexes, handling times were significantly longer at 50 mm flowers than at shorter lengths (P = 0.05 overall, paired t-tests with Bonferroni adjustments). Handling times of males were significantly shorter than handling times of females at 35 mm and 40 mm long flowers (P = 0.05 overall, t-tests with Bonferroni adjustments).
