Extended Data Fig. 5: Late courtship stages and copulation decrease threat responses.

A,B, Fraction of flies exhibiting courtship or defensive behaviour in response to an early (A) or late (B) threat, delivered after 7 s or 4 min of sustained courtship (nearly = 47, nlate = 52). C, Behavioural protocol: the threat is delivered at either 30 s, 5, 10 or 15 min after copulation initiation. Controls for copulation have been observed at the same time point in absence of the threat. (Note that sperm transfer takes ~10 min10.) D, Percentage of flies engaged in copulation 30 s, 5, 10 or 15 min after mating initiation in absence (n = 10,10,10,10) or presence (n = 16,24,21,18) of the threat.
