This volume is dedicated to Gerry Tremewan, a famous Cornish entomologist who worked on Lepidoptera from the age of 12 until his death aged 85, specialising for over 60 years on the Zygaenidae. A foreword by his son Malcolm is followed by contributions from Emmanuelle Briolat, Roger L.H. Dennis, Eric Drouet, Konstantin A. Efetov, Axel Hofmann, Marc Nicolle, Adrian Spalding, Gerhard M. Tarmann, John R.G. Turner, Zoya Yefremova and Hossein Rajaei. The book lists his complete bibliography of 220 papers and books, all the 68 taxa described by him and the 7 taxa dedicated to him. This special illustrated memorial book also includes Gerry's own memoirs in a separate section entitled 'Have Net, Will Travel: Reminescences of an old entomologist'.
