I fish this pattern all year as the bottom fly on any type of setup.

Olive Dredgemerger
By: Larry O Jurgens
Hook: TMC 2457, TMC 2487
Sizes: 12 ~ 22
Thread: Olive UTC 70
Tail: Medium Pardo Coq de Leon Tailing Barbules
Abdomen: Olive, UTC Ultra Wire (Size, Tyers Choice)
Wingcase and Wing Buds: Black Float Vis
Thorax: Brown Olive Superfine Dubbing
Head: Brown Olive Cyclops, or Coffee Montana Fly Co Lucent Tungsten Bead
Other: Super Glue and Hard as Hull “HaH” Head Cement
Notes:
This pattern works well for Baetis/Blue Wing Olives, Caddis and General Purpose when tied in the appropriate sizes.
I tie Caddis and General Purpose patterns in sizes 12~18 and Baetis/Blue Wing Olives in sizes 18~22 with a Coffee or Brown Olive Bead.
This pattern works well for a “searching” pattern when nothing discernible is hatching.
Tying Instructions
Slide bead onto the hook shank to behind the hook eye.
Start the thread behind the bead.
Tie in the tail material and wrap a smooth thread base partway down the hook shank.
Tail length equals the hook gape.
Return the thread to behind the bead wrapping a smooth thread base.
Tie in the abdomen wire behind bead.
Insert the wire end into the bead before tying in.
Overwrap a thread base towards the hook bend equal to the bead width.
Apply a thin coat of super glue to the thread base being careful to not to get glue on the tail fibers.
Wrap the abdomen wire partway down the hook bend covering the thread base.
Break the wire on the underneath side of the hook shank.
Optional: Coat the abdomen with HaH or Super Glue for durability.
Select a #2 pencil lead sized bunch of the wingcase/wing buds material.
Tie in behind the bead and overwrap to the end of the thorax area.
Dub the thorax to behind the bead.
Note: The thorax should be the same width and thickness as the bead.
Pull the wingcase over the thorax are and tie in with 2~3 wraps.
Divide the fibers in front of the hook eye and fold back for the wing buds.
Note: The wing buds should be on the sides of the wingcase, not on the hook shank sides like legs.
Trim the wing buds shorter than the abdomen (length is tyers choice).
Whip-finish using a minimum number of wraps.Optional: Apply 2 coats of HaH to the wingcase and/or to the abdomen for durability.
