Reactions to Sounds by the Wood Nymph Butterfly, Cercyonis Pegala1

That some species of moths produce and receive sounds is now well established. Reaumur (1734, pp. 294-295; 1736, pp. 289-293) first called the attention of scientists to the sound produced by the Death's Head Moth, Acherontia atropos. Many papers on the sounds produced by this and other species of moths have since appeared (cf. Swinton, 1880, pp. 118-127; 205-206 for review of earlier work; Frings, 1955 for refs. to lit.). Moths are also known to receive sounds by means of an auditory organ first described by Swinton (1877, 1880, pp. 243-249). Experimental studies on sound reception by moths and the physiology of the tympanum have been fairly numerous also (cf. Eggers, 1925, 1928 for review of earlier work, Kennel and Eggers, 1933,. Schaller and Timm, 1949, 1950, and Treat, 1955 for more recent studies).
