Abstract
Summary Individual variation has been examined in each song parameter of the decticine bush cricket Platycleis albopunctata. Each individual has a characteristic song within the species specific limits. These limits are defined by the range of variation encountered which may, for many song parameters, be considerable, even within one population. The extent of variation in the spectral parameters implies broad-band reception in these bush crickets. The implications of such variation for the generation of song has also been discussed. Some notes on temperature-dependent variation have been included, amongst which are data showing a hitherto unreported change in the number of syllables in the chirp according to ambient temperature.
