Sitting at the southern limitof Australia's temperate zone, Tasmania is home to a diverse array of mayfliesand renowned fisheries based on them. The state's storied "LambdaDun" hatches bring fishers from all over Australia to try their luck eachsummer on its rivers and ponds. Yet little is known about their behavior andecology, and more than half of the mayflies in Tasmania have never beendescribed. This extensively illustratedbook is the first synthesis of the biology of south-east Australia's mayflies, with a focus on those in Tasmania. It combines information gleaned fromscientific literature as well as more than 30 years of the author's studies andflyfishing experiences. It explores the biology, identification, conservation, ecology and behavior of mayflies, and also includes fishing strategies and flypatterns.
