Step 1: Identify terrestrial feeding and choose a floating daddy pattern
Alright mate, Willy here. A daddy-longlegs fly is a cracking way to try for autumn trout when crane flies are getting blown onto the water. We’ll cover how to spot trout feeding on them, choose a floating daddy, and set up your fly and leader so they sit right. Then we’ll compare leaving it still with giving it a tiny twitch, and work out when to lift into a take. The big thing is reading your swim rather than dragging the fly about and hoping. Watch the real insects and the rises, and you’ll have a much better idea of what to do next.
By the end of this step
Spot likely daddy feeding and choose a floating pattern that suits what you can see.
Check first
Have the correct rod licence where required and permission to fish. Check local trout seasons, autumn closures and venue rules; river and stillwater rules can differ. Wear glasses and check behind before every cast.
Willy’s take
Before casting, watch the swim for a few minutes. Look for long-legged crane flies on bankside grass, insects blowing onto the water, and trout rising nearby. A breeze blowing from grass onto the lake is worth checking, especially along the margins and any lines of gathered insects.
Watch what happens to individual insects. A trout sipping down a stranded daddy is stronger evidence than a splash alone. Repeated rises along the same route suggest a feeding patrol. Get on the fish by covering that route, rather than choosing a swim just because it looks comfortable.
Start with a single floating daddy on a floating fly line. Try a size 10–14 foam-bodied daddy for buoyancy and visibility, or a hackled deer-hair daddy for a less bulky shape. Match the rough size of the insects; bigger isn’t automatically better.
On the bank
Worked example
On a typical stocked lake, a crosswind carries crane flies off rough grass. Trout rise close to the bank where the insects land. Start there with a floating foam daddy, rather than casting straight towards the middle.
Find a daddy-feeding swim
- 1
Watch two accessible banks, keeping back from the edge.
- 2
Look for crane flies on the grass and stranded insects on the water.
