CDC Callibaetis Emerger by Big Y Fly Co.
Callibaetis are essential for fishing in high mountain lakes. These insects serve as a major food source and hatch during the middle of summer, making them a key pattern for anglers targeting trout and other native species.
This emergent fly is designed to be fished in a slow sink or with subtle twitches, mimicking the natural behavior of the real insect.
CDC material provides natural buoyancy, helping the fly maintain a realistic floating action during the emergence phase.

Fished this pattern in a high mountain lake during mid-summer and caught several trout. The CDC buoyancy helped it float naturally and respond to subtle strikes. A realistic imitation that worked well in still water conditions.
Alexander Welch –
Good match for summer fishing. The slow sink action and natural float made it easy to detect when a trout took the fly. Works well with light tippets and subtle presentations.
Brian McLean –
Used it in a remote lake with little fish activity. After a few casts, I saw a few strikes. The emergent action and CDC material gave it a lifelike movement that stood out.
