Little brown stone flies...I should say. You already know the local trout streams are practically littered with...ohnevermind. So, as spring progresses and the creeks start to open up farther and farther you will begin to see more diversity in the active bug life. Midges will still be the prime activity, but you are almost certain to see some tiny stoneflies crawling on your shirt collar. These bugs will be smaller than some of the smallest caddis you will see later in the year, but they will act as teasers to the resident trout who have had nothing to chase all winter. You will find that larger dry flies will begin to work consistently, as well as larger nymphs. Use a size 14 hairwing dry with a size 16 bead-head nymph dropped off behind.
