Description of the four different phonotaxis trials that females crickets (G. bimaculatus) were exposed to

Trial	# Stimuli	Stimuli presented	STD1 stimulus position
Bandwidth (BW)	7	0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2 kHz	1
Duty cycle (DC)	7	10, 30, 40, 50, 60, 70, 90%	4
Frequency (FQ)	9	3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7 kHz	5
Syllable period (SP)	10	23, 28, 35, 39, 43, 48, 53, 58, 67, 81 ms	–

Each stimulus was played back for a duration of one minute per speaker from two different speakers situated at different locations (210° and 90°, respectively). All trials except SP (see text) had two standard stimuli (STD1 and STD2) with the following specifications 5 kHz frequency, 43 ms SP, 50% duty cycle, 4 syllables/chirp and 2 chirps/s. The STD2 stimulus was the final stimulus of a trial (not indicated in the table)
