The bright green new leaves of spring signal the start of another fishing season.  Are you ready for the spring hatches?

You will need a variety of patterns to cover BWO hatches.  Make sure you have a nymph pattern (lower left), emerger (lower right), cripple (middle), dun (upper left), and spinner (upper right).  The patterns shown are all tied small - size 18-20.

March brown patterns:

Top row - Harrop Dun & Rusty spinner

Middle - CDC emerger & March Brown flymph

Bottom - Peacock nymph & brown mayfly nymph

Mature Skwala nymph.

Note: You can use similar patterns as the Saddle-case caddis patterns, just adjust their size and color.

Many options exist for imitating caddis pupa.  The two above, a green flymph (left) and bead-head pupa pattern (right) tied in size 16 will do a good job during a Mother’s Day caddis hatch.
