As the ancient Egyptian seers
predicted, the last full moon of August was certainly the transition moon.
Weather patterns have rearranged favorably. A few nights ago, under the porch light, I
discovered the first great gray spotted sedge (Arctopsyche grandis) of the season.
GGSS is a large insect, the
body about 5/8 of an inch long & the wing about an inch long. The wing is
thick & waxy, like October caddis.
Just as anglers keep a mental
catalogue of the larger fish they’ve caught, so do trout keep a catalogue of
the larger insects they’ve caught – drakes, salmonflies, carpenter ants, wasps,
grasshoppers – & eat them (& the artificial) opportunistically through
the big insect’s respective seasons. The big ones are memorable.
So it is on my home water.
And even though GGSS pupae & adults are most active around dark, the
imitation generally fishes well all day when these insects are present.
As with October caddis, winged
wetfly variants of great gray spotted sedge fish best for me.
