Riband Wave Moth
A small greyish moth occurring in both banded and plain forms. The banded form has a conspicuous dark central band across the forewings.
Did You Know?
Both the banded and plain forms can emerge from the same brood of eggs.
Giant Stonefly
Large aquatic insects whose nymphs require pristine, cold, oxygen-rich streams. Adults are poor fliers and stay near water. Important food source for trout.
Did You Know?
Stonefly nymphs are so sensitive to water pollution that their presence is used by scientists as a living indicator of water quality — no stoneflies means polluted water.
