Arctic Mayfly
A small, delicate mayfly with transparent wings and two long tail filaments. Nymphs are agile swimmers in cold Arctic streams. Adults emerge for a very brief mating flight during the short Arctic summer.
Did You Know?
Adult mayflies live only a few hours to a few days, just long enough to mate and lay eggs before dying.
Two-toothed Goldenring
A large, dark goldenring dragonfly of central European mountain streams. It is distinguished from other goldenrings by two tooth-like projections on the occipital triangle.
Did You Know?
Its larvae develop in tiny trickles of spring water no wider than a hand, unlike most large dragonflies.
