"Big" Midge Adults?

[Joe Billingsley]

Many lakes have large populations of big Chironomids - some up to an inch or larger. The larval and pupal stages are sometimes imitated on hooks as big as long shanked #10's, or even bigger. My question is why isn't the adult stage of these large midges tied more often? I rarely (if ever) see a recipe for a large midge dry fly pattern. Small adults are imitated, but do trout not key in on that stage of the large ones?

Trout eat em on Hebgen Lake. After ice out, the midge hatches up to size 12 get so prolific that balls of midges roll across the lake surface, driven by the wind.
