White Miller

A dry fly, tied #14–18, a summer pattern. It is tied against 1 named insect in this book — July–September.

What it looks like

A drawing, not a photograph, and not traced from one. Its proportions were read off 5 independent reference photographs of the pattern and written down as 5 measured characteristics — wing angle, tail length against the shank, how far a hackle fibre reaches — every one of which had to hold across more than one of them before it could be drawn. What survives across many photographs of a fly is the fly.

A white caddis that comes off at dusk in late summer, sometimes in numbers that whiten the air. Pale all through, which makes it one of the few flies you can actually see at last light. Drawn at #16 — 7.0 mm of shank and 3.5 mm of gape on a Tiemco 100.
#14#16#185 mm
The bare hook at every size this pattern is tied in, all to the same scale. There is no industry standard behind a hook number, so these are Tiemco 100 measurements and another maker's 14 will differ a little.

What it imitates

Each of these is the same hatch record the app's own panel reads, so a pattern recommended on a river card in the app is recommended for one of the insects below.

Tying recipe

In tying order. This dressing is the standard one — these patterns have been in the publicrecord for decades — and materials substitute freely: the proportions and the silhouette are the pattern, not the brand of dubbing.

HookStandard dry-fly hook, sizes 14–18
ThreadWhite 8/0
BodyCream dubbing
WingWhite deer hair or pale elk
HackleCream, palmered

When to fish it

Midsummer evenings on driftless and lower-peninsula water. Start before the swarm is visible; much of the eating happens on the pupa beforehand.

A summer pattern. The insects it matches are active july–september, in water from 60°F to 74°F.

Target species

Rivers it fishes well

Rivers with a page here that sit in the regions where the insects this pattern imitates are recorded. It is a claim about coverage, not a report of a fish caught.
