Angler's Curse Mayfly
A tiny mayfly nicknamed for frustrating anglers who cannot imitate it on hook. Nymphs burrow in fine sediments of slow rivers and streams.
Did You Know?
At just a few millimeters long, trout feed on them voraciously but anglers struggle to tie flies small enough to match.
Microcaddisfly
One of the smallest caddisflies, with adults only 3-4 mm long. Larvae build tiny purse-shaped cases from silk and algae on submerged rocks.
Did You Know?
Microcaddisfly larvae build a new case for each instar, and their final pupal case is so small it is barely visible to the naked eye.
