During my last thread:
Some for this morning, 'Silversedge' mentioned 'Flying Ants'. However like others i had cleared out my seriously under used imiations. You know the ones, 'Ant shaped' thread body, white hackle tips/poly yarn for the wing and black cock hackle tied 2/3rds up the shank.
So with 'Silversedges' suggestion

and my Mothers favourite saying "Oh...just in case"

, i tied up these on #16/18's...just in case.
A water test
Maybe it's a bit too late for them now, but there's always next year.
Cheers Derek.
