Squirrel hair's natural shape and texture realistically mimic aquatic insect nymphs. Its fluttering resembles struggling or swimming insects, strongly attracting insect - eating stream fish like barbel chub and large - eye bream, with great fish - attracting effect.

Soft and tough, squirrel hair resists deformation in water, has good water resistance, and maintains stable physical properties after long - term immersion. It doesn't decay or lose shape easily, ensuring long - lasting fish attraction.

The golden head bead weights the lure. Working with squirrel hair, it gives the fly fishing lure an appropriate sinking speed, mimicking falling insects, reaching fish - active water layers easily, and boosting the fish - catching rate.
