Euro NymphsTRC Baetis
The TRC Baetis combines UV-enhanced materials with an innovative biot wrapping technique for both durability and attraction. By wrapping flexible UV floss through the turkey biot body, this pattern gains significant durability while adding UV properties that make it stand out underwater. Created by Cheech at Fly Fish Food, it offers endless color combinations.

Overview
The TRC Baetis uses an innovative technique where flexible floss is counter-wrapped through the biot body, adding both UV flash and structural reinforcement. This solves the common problem of fragile biot bodies while adding attractive properties. Note that biot bodies typically work best in sizes #14-#16 and smaller—they become difficult to work with on larger hooks.

Fishing Tips
Season
Most effective during spring and fall Baetis hatches (March-May and September-November). The UV properties make it particularly effective on overcast days when natural UV light penetration is reduced.
Presentation
Fish on a tight line euro rig with direct contact to the fly. The slim biot body and tungsten bead sink quickly. Dead drift through likely holding water, paying attention to subtle takes.
When to Use
Deploy during Blue-Winged Olive activity or as a prospecting pattern in waters known to hold Baetis. The UV enhancement makes it visible to fish even in slightly off-color water.
Water Type
Excels in tailwaters and spring creeks where Baetis are prevalent. Works well in riffles, runs, and slower pools. The realistic segmentation of the biot body appeals to selective fish.
Rigging Suggestions
Fish on 5X-6X fluorocarbon tippet. Use as point fly in euro rigs or as dropper below a dry fly during hatch activity. Sizes #16-#20 cover most situations.
Visibility & Floatation
The tungsten bead provides quick sink while the UV-enhanced materials remain visible to fish. The slim profile cuts through current effectively. The fluorescent orange hotspot thread collar adds a trigger point.
