LAWRENCE, TOM - WATER BEETLES OF POLLARDSTOWN FEN (CD)


"What is presented in this CD is a very alien world, a hitherto unheard aural environment that breaks with all our preconceived notions of what underwater life should sound like. All our traditional conceptions and inherent cultural conditioning are overwritten, deemed void and deleted. The work contained in this CD redefines our notions of underwater life and presents a world of alarming sophisticated communication; a myriad of signal generation, perpetuated by a plethora of intelligent species. In this booklet, Pollardstown Fen and the mechanics of insect stridulation are examined before an explanation of the contexts of the sound recordings and the methodologies employed are discussed. Pollardstown Fen is one of the last remaining calcium-rich spring-fed post-glacial valley fens in Western Europe. According to extant research, amongst the plethora of stridulating invertebrates that exist in the aquatic ecosystems of Pollardstown Fen, are the following water beetles and water bugs: Water Scorpion (Nepa cinerea), Greater Waterboatman (Notonecta spp.), Lesser Waterboatman (Corixa spp., Sigara spp., Hesperocorixa spp., Callicorixa spp.), Water Beetle (Acilius sulcatus), Great Diving Beetle (Dytiscus marginalis), Whirligig Beetle (Gyrinus substriatus). Each of these water insects are known to produce sound through a process called stridulation." (label info)
