Stenus Jet Rove Beetle
A small rove beetle with bulging eyes and an extensible sticky labium used to capture springtails. It can skim across water using a surfactant secretion.
Did You Know?
It secretes a chemical that lowers surface tension behind it, propelling it across water at remarkable speed.
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.
