Caddisflies

I used to call these pebble wrapped pupae “perrywinkles” but those are actually little snails. Maybe my parents steered me wrong. The half-inch stalks attached to underwater rocks, swaying in the current, are caddisfly babies, called by some “underwater architects”¹ for the various cocoons they build.
