I clearly remember as a kid some 5 or 6 decades ago sitting in a leaky old wooden rowboat fishing - probably drowning worms - and watching a big old bumble bee on the surface of the lake. Suddenly the biggest bluegill I had ever seen came up and took the bee. Ever since I too have been fascinated by bee flies. While I gave up fighting with hair bodied flies a long time ago, your elegant tie may just have inspired me to give it a try again.
