N0062 - Crane Fly Larva

he Crane Fly Larva is a big, meaty subsurface pattern that trout recognize as an easy, high-calorie meal—especially when water temps cool and fish want to eat with purpose. Crane fly larvae live in soft bottoms and bankside structure, and they get dislodged during higher flows, bank erosion, and seasonal shifts. When that happens, trout don’t pass them up.

Why it works

• Large profile imitates a protein-rich larva trout key on year-round

• Excellent “big bite” nymph when mayflies and midges feel too small

• Stands out in stained water, deeper buckets, and faster seams

How to fish it

• Fish it as the lead fly in a two-nymph rig with a smaller dropper (midge/baetis/PMD) behind

• Target softer edges, undercut banks, deep runs, and slow inside seams

• Add weight and get it down—most takes come near the bottom

• Especially effective in early spring, high-water periods, and late fall/winter when trout are looking for bigger meals

When you need a nymph that can tempt larger trout and turn a slow day around, the Crane Fly Larva is a confidence pattern that earns a permanent spot in the box.
