Abstract: The oak platypodid beetle, Platypus quercivorus, stridulates both during premating behavior and when stressed, as well as spontaneously. When a female was put onto the bark surface of a male-infested log, she began to walk and produce an "approaching chirp," searching for a gallery entrance. When finding one, she entered it and tried to pull a male out. If the male's abdomen became visible, she appeared to push her frons against his elytral declivity and made a "premating buzz" that lasted about 5-10 s. During this buzzing, the male backed out of the gallery in order to allow her in. Females that had been silenced via surgery did not evoke this reaction; thus, males apparently identified females by their buzzing sound. The male then followed the female into the gallery, and produced an "in-gallery chirp" with his posterior abdomen visible. After a while, both sexes backed out of the hole and copulated at the entrance. Both sexes produced "stress chirps" when confined inside a cotton ball, and "spontaneous chirps" when walking alone on the surface of an oak bark piece.
