For the story of the rise of the emerald caddis pupa to a prominent fish attractor, please view my post of 01/01/2012. This post also provides a materials table. The prime caddis season during 2020 coincided with my recovery from mitral heart valve repair, and this circumstance translated to less than normal shrinkage in my inventory of caddis pupa flies. This held true for the emerald version, and consequently I only produced three additional flies in my recent tying session.
My usage of the emerald caddis pupa continues to be fairly consistent, as it ranks only behind a top tier of flies that includes the hares ear nymph and salvation nymph. Hopefully the administration of a coronavirus vaccine and improved personal health will enable me to spend more time on the rivers and streams in the spring pre run off time period, and the emerald caddis pupa will occupy significant time on my leader.
