What it is
Hareline Core C1760 Hopper and Terrestrial is a fly tying hook built on a long, curved shank with a curved shank bend that helps you get a realistic terrestrial silhouette. It has a small barb, a chemically sharpened point, and it stays lightweight for patterns that need to ride naturally on or near the surface.
What to tie with it
Use it for grasshopper, cricket, stonefly, and other terrestrial patterns where that longer, curved profile matters, and for lightweight nymphs when you want a bit of bend in the body shape. It’s also a solid hook choice for tying Stimulators, especially when you’re aiming for that long-bodied, buggy outline.
Flies and the fish they're for
The Stimulator is a classic trout fly, fished as a buoyant attractor dry in pocket water, riffles, and along banks, and it often doubles as a searching pattern when you’re not sure what’s hatching. This hook style also fits realistic hopper and cricket patterns that get eaten by trout during warm-weather terrestrial season, particularly on rivers and meadow streams where fish key on big bugs near grassy edges. With the same shape you can also tie larger stonefly-style dries that are commonly fished for trout on freestone rivers during stonefly activity.
How it compares
It has a similar bend and set of uses to the Tiemco TMC 2302 Terrestrial and Caddis Nymph Hook, but the Core C1760 runs to larger sizes, going up to 4 while the TMC 2302 stops at 6.
