Light Cahill & "Orange" Cahill

The photos and these recipes were submitted by Joe Rist. The light cahill is an important fly in this region and usually begins to appear around mid June and will occur well into August.  If you are fishing a tailwater you are more likely to find light cahills in the lower section since they apparently do not favor the colder water. 

The orange cahill is another cahill which occurs on the Delaware and the Beaverkill, and will be present in the colder water sections of a tailwater. It also appears in June but lasts until mid September, and is a good fly for blind casting when searching for fish.
