Red Blood Midge

Tying the Red Blood Midge is straightforward, making it ideal for beginning tiers, though working at such small scales requires good lighting and magnification. Start with a quality midge hook—size 20 is a good starting point before advancing to smaller sizes. Create a thread base and build a slightly tapered body using red thread or ultra-thin red wire. The body should be smooth and slim, imitating the segmented appearance of the natural larva. Some tiers add a fine wire rib for durability and segmentation, though a thread body alone often suffices.

For increased visibility and effectiveness, consider adding a small peacock herl thorax or a tiny ball of black dubbing at the head. This dark thorax helps trout locate the fly and suggests the developing wing case of an emerging midge. Some variations include white antron fibers or a single CDC fiber as emerging gills, though the simplest versions often work best. The key is maintaining a slim profile—bulky midges won't fool selective trout.

Fishing this pattern effectively requires specialized techniques. In rivers, use a long, fine tippet (9-12 feet of 6X or 7X) and a small strike indicator or sighter. The drift must be completely drag-free, which often means upstream presentations with careful mending. Watch for the slightest movement of your indicator—midge takes are often subtle, appearing as a brief hesitation or slight dip rather than a dramatic plunge. In stillwaters, fish the pattern beneath a strike indicator at varying depths until you locate feeding fish, or use a slow hand-twist retrieve along the bottom.

Winter midge fishing tests an angler's patience and skill. Cold water makes trout lethargic, and rises to midges can be nearly imperceptible. Focus on slow, deep runs and tailouts where fish hold in moderate current. Multiple-fly rigs with the Red Blood Midge as the point fly and a slightly larger midge emerger or pupa as a dropper can help you cover more water and determine what stage trout are targeting. The payoff for this technical fishing is often the best trout of the season, feeding confidently on a reliable food source when little else is available.

The Red Blood Midge emerged from the technical tailwater fisheries of the Rocky Mountain West in the mid-20th century, as anglers on waters like Colorado's South Platte River developed specialized patterns to match the tiny Chironomidae that trout fed on year-round. The pattern's development parallels the rise of tailwater fishing as a specialized discipline requiring fine tippets, delicate presentations, and precise imitations of minute insects.

Blood midges—so named for their distinctive red coloration caused by hemoglobin that allows them to thrive in low-oxygen environments—were long observed by anglers but rarely imitated effectively. Early fly fishers often dismissed midges as too small to matter, focusing instead on larger mayflies and caddis. However, pioneering anglers on technical waters discovered that trout often fed almost exclusively on midges, particularly during winter months and in heavily fished tailwaters where larger insects were scarce.

The simple elegance of the Red Blood Midge pattern reflects the minimalist approach favored by technical nymph fishers. Unlike complex patterns with multiple materials, this fly relies on accurate size, color, and profile to fool selective trout. Its effectiveness has made it standard issue in fly boxes across North America's premier tailwaters and spring creeks, proving that sometimes the smallest, simplest patterns produce the largest, most challenging fish. The pattern continues to evolve with modern materials like ultra-fine wires and UV resins, but the core concept remains unchanged—a slim red body in tiny sizes that perfectly matches one of trout's most reliable food sources.
