Insect knowledge/applying it on the stream

Uh, duh, if you open your *eyes* and *look* at the insects, you can
get a pretty good idea of what they are. Mayflies, caddis flies,
flying ants, stoneflies, et al all look and fly differently. If you
can not distinguish between them, you should probably be spin fishing.

If there is a large rise of a particular insect, then yours should be
something bigger and better - the fish need to differentiate between and
exact replica and the real thing.

Dave - you swore - you said SPIN :-)
