I was researching this Caddis after noticing several enquiries for the fly. In the process, I learned a  few interesting tidbits from this eNature site.

“Female caddisflies drop masses or strings of hundreds of eggs into fresh water, or they attach them to vegetation overhanging water, into which larvae drop…. (Underline my emphasis).  Eggs hatch in a few days but most larvae need a year to develop.”

“These fast-water caddis flies are unusually elegant; they have shiny, dark metallic-colored bodies and glossy wings.” Troutnut.com

I can envision a few strands of careless yellow or orange CDC trailing from the abdomen of an adult Caddis imitation; impressionistic perhaps, pointless perhaps. But more imagination toward a suggestive female adult in the water with trailing egg strands near shore or adrift. I don’t know. Just trout food for thought. Ha! The season is almost over, save the October  Caddis, and now I find this. Well, planning for next late Spring I guess.   Zebra Caddis Pics
