About Small Brown Stoneflies
Many fly anglers are unfamiliar with the brown stoneflies. They have excuses: the insects is small and not as glamorous as salmonflies or golden stoneflies; hatches are rarely intense; and the insects hatch January through April, when many anglers have hung up the rod for the winter. But trout do not ignore these bugs, and when one lands on the water it is soon inhaled by a hungry trout.
Nymphs are rarely taken by trout until the hatch season. By February, however, a nymph pattern dead-drifted near the bottom can pick up a fish or two.
The adults are much more interesting. Females lay eggs sporadically throughout the day, so you won't see big mating swarms. They land on the water and release their eggs--quickly because trout are looking for them and will take them eagerly.
Look carefully in streamside vegetation and on snowbanks. When you find a stonefly (about size 12), match its size and color with a Parachute Black Stone or Elk Hair Caddis.
