T-maze used for paired choice experiments, consisting of 3 clear acrylic tubes joined by an ABS T-hub. During a trial, females could move freely between cages, while each male was limited to his cage via a tether (see Experimental procedure). Female time spent with males (Figures 3, 4) included time in male cages and in 'entry tubes’, where females would often sit with their heads near the cage entrance.
