Glue buzzer.
Quite handy for fish taking static buzzers at a specific depth. This sort of style buzzer became really popular for a while. Personally I'd rather fish seal fur patterns on the slime, but this technique can have its day. It also works quite well on rivers, where I guess they take it for a cased caddis.
Tying instructions:
size 10, black thread tied buzzer shape, with some orange floss tied along both sides of the thorax. The entire fly's coated in Light of Apgai and you have to be careful not not to get it stuck to your fingers - flytying's a bit complicated like that sometimes.
