Hexagenia

Imitates the burrowing Hexagenia limbata mayfly nymph—one of the largest mayflies in North America. Typically olive or brownish-yellow, they live in silty lakebeds and slow rivers.

History:
Famous in the Midwest and Great Lakes regions, Hexagenia patterns are most effective in lakes and lowland rivers during summer. The non-beadhead version is fished slowly near bottom or on the swing before dusk, as fish prepare for the hatch.
