The Mio Orange (pronounced "my-oh"), is named after the town on the legendary trophy section of the Au Sable River in Michigan where I designed and first tested this pattern. It is an abstract, competitive style pattern suited to represent multiple species of insect larvae that competing/traveling anglers may encounter. It is also designed for being presented at any depth of a river's water column, and for even being able to tumble along the river bottom or structure with its up-turned Partridge of Redditch jig hook.
When fishing on timeline--partaking in a tournament or just on "a trip to the store" for your spouse or loved one-- there are two things an angler must be able to do quickly when arriving to their spot in order to get the most from their outing: cover the entire water column and present a pattern that imitates multiple species of insect larvae at once--not just one specific insect pattern at a time. By adjusting size of hook and weight (bead, wire, etc.) to suit water conditions, the Mio Orange can imitate numerous types of pale insect larvae that have a slender, segmented abdomen and pronounced thorax (mayfly, baetis/bwo, etc.).
Hook: Partridge Jig size 14
Bead: 3.5mm slotted tungsten
Tail: Grizzly Hackle fiber
Abdomen: Cream thread 70 denier and copper wire size Brassie
Thorax: Dubbing mix of light hare's ear and UV Orange
