Mayer's Tungsten Titan Tube Midge in Red/Black is a #14 midge larva from Montana Fly Co., weighted with tungsten that gets the fly down fast in deeper runs and faster water. The tube body gives it a translucent, segmented profile that looks like a real midge larva, and the red and black colorway matches the naturals trout eat on the bottom year-round. Midges are a staple on tailwaters and spring creeks, where trout feed on larvae even when nothing is hatching. Fish it dead-drifted under an indicator or as a dropper behind a dry — a go-to midge for selective tailwater trout.
