These newly hatched insects are vulnerable targets, often trapped in the surface film while waiting for their wings to dry. When a hatch is frequent, fish—especially large, experienced trout—become highly selective, focusing entirely on the specific silhouette and color of the prevailing Dun.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003e\u003cb data-path-to-node=\"5\" data-index-in-node=\"0\"\u003eJ:son Mayfly Dun – Slate Grey (#18)\u003c\/b\u003e \u003cb data-path-to-node=\"5\" data-index-in-node=\"36\"\u003eThe Small-Body Technical Specialist\u003c\/b\u003e\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eThe J:son Mayfly Dun in Slate Grey, size #18, is a masterclass in precision.

On overcast or drizzly days, these small insects appear darker and more greyish against the water.
