Squirminator

How it's tied

The Squirminator is a simple pattern. The body is typically formed from a soft, stretchy material called Squirmy Wormy (hence its name), wrapped around the hook shank to create a cylindrical shape that imitates an aquatic worm. A wire ribbing or thread is often used to secure the Squirmy Wormy material and add segmentation. The thorax is made from dubbing, which can be natural or synthetic, to add bulk and provide a contrasting texture. The head is finished with a tungsten or brass bead to add weight and attraction.

What it mimics

The Squirminator is designed to imitate aquatic worms, such as annelids or midge larvae, which are a common and essential food source for many fish species. 

Where it's used

The Squirminator is particularly effective in high water or discolored conditions when fish are more likely to be feeding on aquatic worms or other dislodged subsurface insects. To fish the Squirminator effectively, use techniques such as dead drifting or nymphing with an indicator or tight line. 

Because of the way it's tied, it's color and the it's application it's very similar to the San Juan Worm.
