Its funny when you think about it. Just about every other man, woman and child in the Northern Hemisphere is running for the bug spray, installing insect zappers and windows screens. And yet we fly fishers are giddy with the prospect of summer hatches, peering into our auto grills, staring at outside lamps, kicking our way along streamsides and seining the waters.
There’s stoneflies, mayflies, caddis all taking to the wing on rivers and streams, lakes and ponds across the US. Don’t forget the steady drip drip of terrestrials, ants and beetles from overhanging foliage, and of course the delights of summer hopper fishing. And on tailwater systems like the White, even in high water, there are plenty of midges about.
But preparation for the summer ahead we thought this weather radar image might help kickstart your imagination, showing as it does a huge mayfly emergence on the Mississippi River in Wisconson

The loop just before 9pm and track the hatch over 90 minutes, (we are guessing Hexagenia because of the hour) and clearly shows the upstream drift of the hatch. For more details on the hatch click here.
