Hi Don, Thanks for the response. As I indicated, many an effective pattern has been devised which incorporates thransluscent antron. Gary's Diving Caddis but one of them, the Diving Baetis Spinner another. Both patterns feature a clear antron downwing.
In the latter case, the spinner crawling downrocks and plant stems (and often angler's waders<G>) trapped air for sure encases the insect making for a silvery sheen. Fishing softhackles (originally North Country Spider) in the film can be a devastating technique, as you have also found out ;-) Cheers, Hans (sub-surface) bubble doubter still ;-)
