This compact 126-page guide offers an impressive depth of information that makes it an essential field companion for anyone interested in riverflies.
The book opens with historical context, tracing riverfly study back to Macedonia in 1420 and the first published fly illustrations in 1496. Macadam enriches this with fascinating cultural references, from the mayfly symphony orchestras in France to German airships named after these insects.
What truly sets this handbook apart is its commitment to accessibility. The methodology section emphasises affordable, DIY approaches – kick sampling with homemade equipment, bankside sorting with jubilee clips on broom handles and kitchen sieves, even using umbrellas as collection tools. Macadam ensures cost is never a barrier to participation, making citizen science genuinely inclusive.
The habitat guidance is exceptionally practical, providing specific species examples for environments: pools versus fast-flowing water, cobbles, ditches, garden ponds and even snowy Scottish streams. The photography section is equally helpful, explaining how to create simple aquariums for specimen photography, managing water reflection, and maximise phone camera capabilities.
Part 2 delivers comprehensive coverage of mayflies, stoneflies and caddisflies. Each group receives detailed treatment with high-resolution photographs of both larval and adult stages, charts showing seasonal occurrence in flowing and standing water, and captivating facts such as Kageronia fuscogrisea, a mayfly species persisting for 40 million years, or how Ian Wallace describes the Elizabethan “cadice men” who sold caddisfly cases as coat decorations. These details consistently elicit ‘wow’ moments that deepen appreciation for the subject.
The conservation section (Part 3) addresses modern challenges comprehensively: bridge impacts on adult movement, solar panels and car paint causing egg-laying confusion, urbanisation, invasive species, pollution and climate change. Macadam’s wealth of experience is evident throughout.
For practical identification, the book lists essential publications for each group and details affordable rearing setups, including instructions for recording mayfly drumming behaviour. The seasonal charts and identification plates make this genuinely useful streamside (with a protective cover, naturally!). This handbook successfully balances scientific rigour with accessibility, making it perfect for both newcomers and experienced enthusiasts seeking a portable reference guide.
