Mediterranean Webspinner
A small, brown webspinner native to the Mediterranean region. It constructs silk tunnels on rocks and walls, and reproduces parthenogenetically in many populations.
Did You Know?
Many populations consist entirely of females that reproduce without mating, a rare trait among insects.
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.
