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.
Pale Dead Leaf Mantis
A light-colored dead leaf mantis from the Para state of Brazil. Its paler coloring mimics sun-bleached dry leaves on the forest floor.
Did You Know?
Its pale variant mimicry targets a different niche than its darker relatives, matching drier leaf litter.
