Dry FliesKate McLaren Variant

The Kate McLaren is a traditional Scottish loch fly, and this dressing is Hans Weilenmann's variant on it. A black seal's fur body under a palmered black cock hackle sits beneath a golden pheasant crest tail, oval silver tinsel rib, and a front hackle of cree cock. It is fished as an attractor rather than tied to any specific insect.

Kate McLaren Variant fly pattern - imitates Attractor tied for Trout

Overview

The black seal's fur body is ribbed in oval silver tinsel and palmered its full length with black cock hackle, then finished with a cree cock hackle at the head and a golden pheasant crest tail for movement and flash. That double hackle lets the fly ride in or just under the surface rather than sit fully awash like a plain wet fly. Hans Weilenmann built this as a variant on the traditional Kate McLaren, a longstanding loch-style pattern rather than an imitation of any single insect. It works as a searching attractor on stillwater and moving water alike, often fished as part of a team of flies rather than alone.

Behavior & Presentation

Natural Behavior: The Kate McLaren imitates no single natural insect; its flash, movement, and dark silhouette are built to trigger a strike as a general attractor rather than to match a specific hatch.

Where Trout Eat It: Fish take it in the same lies where they take any searching pattern, along drop-offs, over structure, and in the surface chop on stillwaters, or in faster runs and pools on rivers.

How to Fish It: Traditionally fished on the top dropper of a loch-style leader and dibbled across the surface in the last few feet of the retrieve, so the palmered hackle pushes a wake; on rivers it also works swung or twitched across current.

Best Water: Wave-chopped stillwaters and loch-style boat fishing, plus faster runs on rivers where a searching wet fly gets noticed.

Strike Type: Takes to a dibbled fly are often an aggressive surface slash rather than a subtle sip, since the fish is reacting to movement and silhouette rather than inspecting a natural insect.

Fishing Strategy

Rigging Suggestions: Fish it as the top dropper on a multi-fly loch leader, or as a single searching wet fly on a short leader when covering river runs.

Seasonal Timing: Useful through the open water season on stillwaters, with no tie to a particular hatch window.

Pro Tips: On stillwaters, work the boat so the retrieve finishes with the fly dibbling in the surface chop, since much of this pattern's action comes from that wake rather than the drift itself.
