Figure 6. Kinetic diagram of courtship behaviour based on 50 successful (A) and 50 unsuccessful (B) courtships.

For each behavioural step (in boxes), the frequency of transitions to other courtship steps is indicated by an arrow and by adjacent figures giving the number of each type of transition (from [52]). Interruptions of the general behavioural sequence are noted by “I”. “Following” of a female by the male during courtship, noted as “F”, involved in 80% of the cases short flights. In (B), courtship stopped at the flickering (6 cases), thrust (9 cases), attempting (32 cases), genital contact (2 cases) or “F” (1 case) steps.
