Spro Larva Mayfly Micro Spinner 5cm 4g

Spro Larva Mayfly Micro Spinner — Insect-Imitating Vibration Lure for Predators

The Spro Larva Mayfly Micro Spinner is a compact, finely detailed spinner built to fool trout and other predatory fish that key on insect and small baitfish prey. At just 5 cm and 4 g, it fits naturally into the strike zone of wary fish while generating strong underwater signals.

Realistic Insect Profile That Triggers Strikes

Every detail on this lure is designed to convince: a larva-shaped body with holographic fish eyes, rubber legs, and glinting tinsel elements combine to create a lifelike silhouette. The insect wing spinner blade completes the imitation, making this spinner a convincing stand-in for the mayfly nymphs and larvae that trout, perch, and chub actively hunt.

Fast-Rotating Blade for Long-Range Attraction

The spinner blade rotates quickly even at low retrieve speeds, producing strong vibration and flash that draw predators from a distance. This dual action — vibration and rotating blade — works across a range of water types, from clear chalk streams to stained river pools, giving the lure consistent appeal when fish are spread out or holding in deeper runs.

Choose the Right Variant

All variants share the same 5 cm length, 4 g weight, size 10 treble hook, and insect wing spinner blade. The differences between them lie in tail dressing and swimming action, which influences how the lure behaves and where it performs best.

• Rubber legs + tinsel elements / Vibration, rotating blade — the current variant; balanced all-round action with added flash from tinsel, well suited to trout and perch in clear to lightly coloured water

• Rubber legs + tinsel elements / Rotating blade with vibration — similar dressing, blade-led action; good for faster currents where the blade needs to dominate

• Rubber legs (no tinsel) / Vibration — subtler profile, reduced flash; a quieter choice for pressured or clear-water fish

• Rubber legs + tinsel elements / Vibration, rotating blade (additional colour variants) — same specification as the current variant in alternative colour options
