The response of the moth (Amphipyra pyramidea L.) to stimuli that simulated the echo of it's own clicks (retranslated signals). All three recordings were obtained during one experiment with the same moth. In every recording there were 12 stimulus clicks.

Thick horizontal solid line, moth's movements in a horizontal plane; vertical lines, moments of echolocational signal emission by the moth; The horizontal scale, time from the beginning of the recording, in seconds; white boxes, periods of readiness of the setup to retranslation; vertical white lines (against the background of stimulation), moments of retranslated signals appearance.
