Adult caddisflies, also known as sedge flies, are well known to fly fishermen, who imitate them with artificial flies. Moth recorders are also familiar with the group, finding some species in their light-traps.
As well as colour photographs of a representative species from each family, key information is given on the habitats, flight period, wing length and other useful identification characters (number of spurs on the legs, presence of ocelli, number of palps). In fold-out chart format, this guide is small enough to put in a rucksack (folds to B5 size - approx. 24 x 18 cm / 10 in x 6.5 in) and has a splash-proof laminated coating for protection in the field.
