Warning—this week's podcast with biologist Michael Miller [36:28] is not exactly uplifting, in fact it's downright depressing. I feel that neonic pesticides are the main reason we have seen dramatic declines of insects on our trout streams and may be even more of a threat to invertebrate populations than climate change. But it is a problem we can remedy more easily than climate change because it's mostly a problem in the United States (Canada and the EU have either banned or greatly restricted their use). I hope this podcast makes all of you take action and raise your voices to get the EPA to ban these dangerous chemicals. On a happier note, we have some wonderful questions in the Fly Box this week, including: It's great to hear that Tom gets skunked as often as the rest of us. Why did I see mayflies when I was a mile from the nearest stream? Do bright fly lines spook fish? Why were fish slashing at my streamer without me hooking them? I am having problems casting a 15-foot leader Where should I take my sons fishing in the Bozeman/Livingston area if I can't afford a guide?  If I hook a fish deep in its throat, should I try to get the fly out or cut the tippet? Can I get closer to fish in a riffle? What are Tom's top 5 trout flies? I am losing a lot of fish on my 10-foot 3-weight rod. What should I do differently? Where do big trout tend to live in a river?  If I am catching just small fish will there be any big fish around? I can't get my floating line to float well, even after cleaning it. What can I do?
