When fishing a stretch of water that is under heavy assault the Olive Hare's Ear is sure to be just what is required. Fished at the bottom of the river or lake this fly can be used to mimic a lone drift nymph which is guaranteed to be a major success on even the most difficult stretches of water. The lethal capabilities of the Hare's Ear Olive is what positions it in our category of "must haves". Another great carp fly.
