Sand-Dwelling Caddis
A caddisfly whose larvae build flattened shield-shaped cases from sand grains. The wide case acts like a snowshoe, preventing the larva from sinking in soft sediment.
Did You Know?
Its case has lateral flanges that distribute weight and prevent sinking into soft sand.
Caenis Mayfly
One of the smallest mayflies, often called the 'angler's curse' because trout feed on them selectively. Larvae inhabit slow-flowing rivers and lake margins.
Did You Know?
Caenis mayflies are called the angler's curse because their tiny size makes matching them with artificial flies nearly impossible.
