I get a lot of questions about midges and their life cycle, so I thought I would invite a professional entomologist to give us an overview of these insects and how to imitate them. Rick Hafele [3816] has not only been an entomologist all his working life, he's also a superb angler and fly-fishing author and perhaps one of the best authorities on aquatic entomology we have. Learn about what color midges to imitate, which part of their life cycle is most important to trout, and how to effectively fish these imitations. In

The Fly Box this week, we have some thought-provoking questions and some terrific suggestions from listeners, including:

I have used both rubber and felt soles and I still have problems wading. I am in good shape and have good balance. What wading shoes do you suggest?

I witnessed a huge hatch of insects but only caught largemouth bass. Is there a depth and current speed where fishing a dry fly is futile?

What type of poly leader would you suggest for my 5-weight rod?

How long should my leader be when fishing a poly leader?

What CFS do you consider safe to wade in a river?

If I catch a wild brown or rainbow in a brook trout stream, should I relocate that fish below a waterfall?

What is the purpose of releasing large hatchery brood stock trout into wild trout streams? Do they have any effect on a wild trout population?

How would you fish a slow, tannic river with a mud and sand bottom?

How long do you stay in one section of a river?

Should I match the diameter of the butt section of my leader to the diameter of my fly line?

What should I do if I hook a large striped bass and it thrashes close to me but does not take line. Should I try to get the line on the reel?

Some great tips from a South Dakota angler on how to find superb fly fishing close to home.
