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.
Giant Silk Moth
A large western North American silk moth with reddish-brown wings featuring bold white crescent markings and a red-and-white banded body. It is the Pacific coast counterpart of the cecropia moth.
Did You Know?
Hyalophora euryalus can hybridize with the cecropia moth where their ranges overlap, producing fertile offspring in a zone of intergradation.
