Sand-Case Caddisfly
A caddisfly whose larvae build smooth, curved cases entirely from fine sand grains cemented with silk. Adults are dark with hairy wings.
Did You Know?
The curved sand-grain cases built by these larvae are so precisely constructed they resemble tiny miniature architectural works.
Bombardier Beetle
Defends itself with a boiling-hot chemical spray ejected from its abdomen at over 100°C. The reaction involves mixing hydroquinone and hydrogen peroxide.
Did You Know?
The bombardier beetle fires its chemical spray at 100°C in rapid pulses of about 70 per second, allowing its internal reaction chamber to avoid exploding.
