Several
Isonychia bicolor nymphs had recently crawled out onto these rocks to emerge, leaving behind their telltale
shucks (Shuck: The shed exoskeleton left over when an insect molts into its next stage or instar. Most often it describes the last nymphal or pupal skin exited during emergence into a winged adult.).

This is the skin a brown drake dun shed when it molted into a spinner. Many of these were on the surface one afternoon, having been blown in after the flies molted on overhanging alders. They were our most noticeable sign of an intense brown drake hatch the previous night and a spinner fall to come.
