Crane Fly
Tipula spp. — Daddy Long Legs, Daddy, Leatherjacket (larva)
When autumn daddy-long-legs blow onto rivers and lakes in August and September, trout abandon all caution for these clumsy, irresistible mouthfuls.

Lifecycle
The Crane Fly is a terrestrial insect whose aquatic relevance is entirely accidental — the adult does not hatch from water but from the soil. The larva (the leatherjacket) lives in soil for up to 11 months feeding on plant roots. The adult crane fly is a poor flier, and in late summer and autumn, numbers of adults are blown from bankside meadows onto the water surface.
Peak months
Few flies inspire more excitement in trout than a flailing crane fly. A large 'Daddy' pattern is a confident, aggressive offering that provokes equally confident, aggressive responses. Even the largest and most wary wild brown trout will cross metres of open water to take a well-presented crane fly.
Fishing tips
Reading the Wind
Position yourself on the downwind bank or shore — this is where cranefly will accumulate on the water surface. On a windy August day, walk the bank before fishing to observe where daddies are landing and where fish are rising.
