Ephemera Hi-Viz

In fly fishing, Ephemera refers to a genus of mayflies — specifically, large burrowing mayflies often imitated by dry flies and emergers. These insects have very short adult lifespans (hence the name Ephemera, meaning “short-lived”), but they play a crucial role in trout diets during hatches.

Key facts for fly fishers:

• Hatch Timing: Often hatch in late spring to early summer.

• Appearance: Long tails, delicate wings, and a graceful upright posture — the classic mayfly silhouette.

• Popular Patterns: Ephemera danica is one of the most iconic European species, often mimicked by classic dry fly patterns like the Green Drake.

• Fishing Tip: During a hatch, trout will rise steadily — matching the size and color of the Ephemera can lead to explosive takes.
