Water Strider
Walks on water using hydrophobic leg hairs that trap air. Each leg has thousands of microscopic grooved hairs. Can detect prey vibrations on the water surface from centimeters away.
Did You Know?
Water striders have over 1,000 microscopic hairs per mm on their legs — each hair has nano-grooves that trap air, making their feet essentially unwettable.
Yellow Sally
A bright yellow stonefly common in European upland streams. Nymphs are omnivorous, feeding on both algae and small invertebrates.
Did You Know?
The vivid yellow color serves no known warning function and fades quickly in preserved specimens.
