"Blue" buzzers

[Dryfly]

While fishing a local stillwater recently, I was surprised by a fellow angler who was catching trout, one after the other on a black buzzer, with an "electric" blue thorax. No one else on the water was catching at anywhere near the same rate, and I wondered if anyone out there has had any success with this fly, or was it a case of "right place, right time"?

Surprising no-one has commented. I have no experience of that particular fly, but any material that gives the thorax a bright or shiny appearance is likely, under the right lighting conditions, to simulate how the thorax looks as it splits at the "emerger" stage.

 

It seems well worthwhile to always carry a few such "caricature" buzzer variants. Just for interest, what were the lighting conditions that day?

Thanks Vagabond,

It was a very windy day, reasonably bright, quite cold, in fact common "early season" weather. As a point, this particular fly is quite popular in this area, however I tend to think that it was the "flash" rather than the colour that made the difference.

Any other thoughts?
