Definition of green drake in English:
1The green subadult of certain mayflies.
- Genus Ephemera, family Ephemeridae
- The natural diet of loch trout is more varied than most care to admit and be prepared for trout taking midge, stonefly, sedge, beetles, nymphs, olives and mayfly (yes green drakes do hatch in profusion north of the Watford gap!).
- About a week after opening day, green drakes - big, pea-colored mayflies - start hatching, allowing anglers to sight-cast to 20-plus-inch rainbow trout.
