Distance to nearest neighbouring female in a large cage that contained 20 H. virescens females and 17, evenly distributed, flowering Nicotiana attenuate plants. Females are initially randomly distributed throughout the cage but as scotophase progresses and the females start calling the distance to their nearest neighbour decreases. The distribution of moths differed significantly from the simulated data only during the last four time points (Tukey contrasts) which coincides with the time that most moths are calling. Legend: H. virescens represents the distance to nearest neighbour of the female moths; Simulated represents the distance to the nearest neighbour in a simulated data set where a random distribution throughout the cage was assumed.
