Serendipity indeed! This is a versatile pattern that can imitate midges and caddis pupa easily with a simple change in size and or color. Typically we see this pattern in red but it can also be tied in brown (seen here) olive or black. With only a couple of materials this fly is a great option if you need to fill a box fast with really effective flies. I like to fish this pattern as my lead fly keeping it slightly higher in the water column than my point fly.
