This Saturday I came to an unusual situation on my favorite stillwater: the expected buzzer hatch did not materialize - I suspect sudden change in air pressure, accompanied by drop in temperature of about 15°C was to blame - but some fish never the less were rising. No insect activity was apparent and the fish ignored all my flies: both dark and pale mayflies, caddis flies, beetles and daddy long legs I kept changing in my increasing desperation.
I finally succeeded in provoking a couple rainbows to attack a red & white lure; autopsy showed that the cause of the rises was a fall of rather large aphids, which were carried by wind from surrounding aspen trees. Until then I had no aphid in my fly box, a sad fact I set today to rectify.
