You can have a fly box full of carefully tied patterns and still find yourself watching trout rise without knowing what to tie on next. Recognising an insect is useful. Turning that observation into a fishing decision is another matter.
That is the practical problem at the heart of The Hatch Code by Andy Kitchener, now available at Fyne Tackle. Here’s a look at what the book covers and who it is aimed at.
Look beyond the insect’s name
“A trout does not read Latin. It reads vulnerability.”
That memorable line captures the book’s approach. Insect life stage, size and colour come before species names. Rather than making fly selection a memory test, The Hatch Code encourages anglers to observe what is happening on the water and use those clues to guide their choice.
For anyone who has recognised a hatch but still struggled to interest a fish, that distinction is appealing. Knowing an insect’s name is not the same as understanding which stage of its life your fly needs to represent.
Reading before casting
The opening part focuses on practical entomology, a five-minute arrival audit and reading rise forms, including what they can and cannot tell you.
The book then considers light, wind, water temperature and barometric pressure alongside hatch timing. The emphasis is on the conditions in front of you, rather than relying on a calendar alone.
It is a practical starting point: observe first, then choose your fly for a reason.
What is inside?
The Hatch Code contains 24 chapters across six parts. It moves from reading the water and understanding conditions to the main food groups, fishing different waters, pattern choice and scientific identification.
Olives, mayfly, sedges, midges and buzzers feature alongside beetles, crane flies, stoneflies and signal crayfish. The focus is on life cycles, timing and the vulnerable stages that matter to anglers.
Throughout the book, 54 “Angler’s verdict” summaries give the practical bottom line in a sentence or two. Quick-reference field guides offer another way to return to useful information without rereading a whole chapter.
From chalk streams to Scottish lochs
For anglers fishing around Argyll, the inclusion of Scottish lochs and rivers is particularly relevant. The book also covers chalk streams, reservoirs and stillwaters, exploring how different waters influence your approach.
That breadth makes it worth considering if your fishing takes you between different settings and you want to understand the reasons behind your choices, rather than simply carry a list of patterns.
Changing waters
Chapter 7, “Changing Waters: Pollution, Rivers and Hatches”, addresses sewage discharge, agricultural run-off and rising water temperatures, with sources, and considers what anglers can do.
Alongside its discussion of changing hatch timings, this gives the book a focus on the waters we fish today, rather than assuming familiar seasonal expectations will always be enough.
Who is it for?
The Hatch Code is aimed at anglers who can cast but want a more informed approach to fly selection. That includes improvers looking to move beyond guesswork and experienced fishers trying to understand refusals or changes on familiar water.
It does not assume specialist knowledge of insect names. Its emphasis is on connecting what you see with what you do next.
A note on the illustrations
Photographs are credited individually throughout, including work by Cyril Bennett MBE, Don Stazicker and Mark Barrow. Some explanatory diagrams and illustrations were produced digitally, including with AI tools, as disclosed in the book’s front matter.
The species identification plates in Chapter 24 are built from real photographs. That distinction is useful for readers who want to understand how the different visual materials were produced.

If you want to approach your next difficult rise with better questions, rather than simply another fly change, The Hatch Code is a book to consider for your fishing shelf.
