Fly Hatches on Yellow Breeches Creek
As on most of the limestone streams fly hatches
have diminished greatly over the last 30 years on the
Breeches. At one time the Breeches had a pretty good
Hendrickson hatch (Ephemerella subvaria). In the
last couple of years this hatch has picked up somewhat on
certain sections of the stream. The stream also enjoys
scattered hatches of the Spotted Sedge (Hydrospsyche
sp.) at various times of the year. You also find a variety
of Cahills (Stenonema sp. and Stenacron sp.)
as well as the Blue Winged Olives (Baetis tricaudatus
Dodds) which emerges throughout the year.
You find the Yellow Brown Stone
(Acroneuria sp.) and the mayfly, the White Gloved
Howdy (Isonychia bicolor).
Lots of midge larva (Chironomids) and scuds
(Gammarus sp.) Of course, the big late
season hatch is Ephron leukon, or the White
Fly. Want to know what the nymphs look like.
Well try this emerging nymph that I captured on a slide
and tie something similar.
