Many emerging flies will die in this final step, trapped in the
surface film, they"ll drown or as they stand still they"ll
be an easy prey for trouts and other fish (even in an aquarium). Many
will never fly

The
emergence had started and was going well . The wing had started to
unfold and then one, then the other get in contact with the water, get
wet and it is over, incapable to unfold the wings and to rise them,
trapped in the surface film, the fly will drown in a few minutes. |

Another danger lies below the surface, the fish, a trout would
have taken the nymph in one gulp, but it was a fair size for the
one inch stickleback and as long as the nymph was moving , it
would not dare to approach. But as the nymph was stilled by the
emergence, the attack is brutal and kill the nymph. |
Taken
in one corner of the aquarium, 3 examples of dead flies on the surface,
wings still folded and one folded the other stuck in the water,
and top right an abdomen, part of a fly taken by a fish.
On a river, the trouts see many emerging flies, the ones
trapped in the surface film are easy prey and are as tasty as the
ones ready to fly off
When fishing or flytying, we should remember that.
