Did You Know?

Tiny hydrophobic hairs on its legs trap air and repel water, allowing it to stand on the surface without breaking through.

Horned Aphid

A social aphid from East Asia that forms colonies defended by sterile soldier nymphs with horned heads. They live on styrax trees and produce a single soldier caste.
