QuietNoises (Field 1)

"In the ground beetle (Broscus cephalotes) it is particularly impressive to watch their reflex of playing dead (Thanatose). If a danger threatens, many bugs lapse into complete immobility. Many spread their legs in spasmodic rigidity wide out from their body, so these cannot be bent in; others pull the extremities completely into themselves in order to deprive the enemy of any attack opportunities ". (Adolf Horion: coleopterology for nature lovers, Frankfurt / M, 1949).
