Response of a spontaneously walking female cricket to close antennal stimulation. The mesh begins to approach the cricket shortly after the video clip begins. The cricket makes its first antennal contact with the approaching mesh after about 2 s and displays an initial fast avoidance response. This transient response is followed by antennal exploration of the stationary mesh. The video was recorded at a 60 Hz frame rate and subsequently down-sampled as well as compressed for publication.
