Movie 4

‘Buzz’ response of stage 1 and stage 3 larvae
(A) Showing examples of stage 1 larval behaviour before, during, and after presentation of three consecutive Buzzes (only behaviour in response to the first Buzz was analysed in Figure S4). The white dot in the lower right panel indicates the presentation of the Buzz. Note that the animals startle in response to the Buzz, i.e. hunch and slow down, and then turn.
(B) Likewise showing examples of stage 3 larval behaviour before, during, and after presentation of three consecutive Buzzes (only behaviour in response to the first Buzz was analysed in Figure S4). The white dot in the lower right panel indicates the presentation of the Buzz. Note that the animals startle in response to the Buzz, i.e. hunch and slow down, and then turn.
