Sulphur Parachute Sulphurs are small mayflies with a yellowish-tan body. They are most common in the summer and early fall. Besides having a few Blue Wing Olive patterns, anglers should also carry a few sulphurs. Adams A good, all-around, impressionistic mayfly pattern that is important both early and late in the season since it can represent a Hendrickson in late April or a Slate Drake in September. The spinner is the last stage of the mayfly's life cycle.
Aquatic insects begin as nymphs then turn into duns and finally die as spinners.
It's easy to locate spinners. They have translucent wings and a very long tail. As they die and lie on the water, trout find them to be easy pickings. The Rusty Spinner can be tied from size 14 down to 20 and represent a good imitation of the last phase of a mayfly. Wulff Named after angler Lee Wulff, these flies are heavily hackled and are listed in my books as attractors meant to imitate nothing in particlar and something in general.
