Griffith's Gnat

Griffith’s Gnat

A timeless and highly effective pattern, the Griffith’s Gnat is one of the best all-around dry flies for imitating midges and small adult insects on the surface. Its simple, buggy profile makes it especially effective when trout are feeding on clusters of midges or other tiny insects.

Floating low on the water, this pattern excels in calm conditions, slow-moving water, spring creeks, and during midge hatches when fish are keyed in on smaller prey. It’s a must-have fly for year-round fishing, particularly during colder months when midges are most active.

Fishing Tips

Fish on light tippet with a drag-free drift during midge hatches, especially in slow pools, tailwaters, and spring creeks where trout are feeding selectively on tiny surface insects.
