okay, photo was wrong.
i must say that i don`t know if the fly that i mean in englisch breadfly is. in german it`s "brotfliege" and i have it one on one translated. this fly is used for carp fishing and is so successful that it is on some waters in germany not permitted. i have one photo, but i don`t know of this is a good one.
if anybody else knows information over the breadfly or have a foto of it send a reply. thanks.
