Reunion Flightless Weevil
A flightless weevil with fused elytra endemic to the island of Reunion. Its inability to fly has made it vulnerable to habitat fragmentation.
Did You Know?
Flightlessness evolved independently in many island beetle lineages as an adaptation to windy conditions.
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.
