A red flag: an experimental analysis of the function of pink colouration in males of <i>Calopteryx haemorrhoidalis asturica</i> (Odonata: Calopterygidae).

However, the GLMM analysis indicates that the treatment did not have a significant effect on the mating rate ( F 1,42.1 = 2.22, p = 0.144), time was close to significance ( F 1,42.0 = 3.45, p = 0.070), but the interaction Treatment*Time was not significant ( F 2,42.0 = 0.52, p = 0.477), indicating that the pink colour was not relevant in mating success.
