Overview
Tim Didas created this unusual pattern with a name that reflects its odd appearance, yet it consistently produces results. The design features an unconventional material combination that creates a buggy, impressionistic silhouette rather than exact imitation. Dubbed body and unique hackle configuration give the pattern distinctive movement on the water. Despite its unorthodox appearance, the Squonker triggers strikes through profile and motion rather than precise matching. Effective as a searching pattern in varied conditions.
Materials
Hook: Lightning Strike SN1 #8
Thread: Black 6/0
Rib: Tag end of tying thread
Body: Pine Squirrel, natural or dyed
Wing: Pine Squirrel, natural or dyed, narrow zonker strip
Collar: Pine Squirrel, natural or dyed, in split thread 'loop'
Behavior & Presentation
Natural Behavior: Evening hatches produce clumsy landings that create audible splashes attracting fish to the surface. Anglers fish low-riding patterns during dusk because the sound and struggle draw confident takes.
Where Trout Eat It: Fish intercept crash-landed caddis from the surface film in smooth runs, pool tail-outs, slicks, and slower riffles.
How to Fish It: Use upstream cast with drag-free drift. The low-riding profile imitates spent adults flush in the film without twitching during selective feeding.
Best Water: Focus on smooth runs, pool tail-outs, slicks, slower riffle edges, and calm flats where fish have time to inspect flush-floating offerings.
Strike Type: Watch for subtle sips and delicate takes as selective fish refuse higher-riding patterns but confidently take low-profile presentations.
Fishing Strategy
Rigging Suggestions: Employ a 10-12 foot leader with 5X or 6X tippet for delicate presentations. Light floatant application maintains the low profile that makes this pattern effective.
Seasonal Timing: Most effective May through October during caddis and mayfly activity, with peak performance during evening rises when multiple hatches overlap.
Pro Tips: The flush-floating design triggers takes from selective fish that refuse higher-riding patterns. Particularly effective during spinner falls.
Entomology
During evening flights, caddisflies crash-land on the water creating prominent surface disturbances that echo across quiet pools. Trout key into these auditory and visual cues, rising confidently to engulf the struggling insects before they can regain flight.
