Ironclad Beetle
Has one of the toughest exoskeletons of any insect — it can withstand forces 39,000 times its body weight. Even entomological pins bend when trying to pierce its shell.
Did You Know?
This beetle is nearly indestructible — its exoskeleton can withstand being run over by a car. Engineers studied its shell design to develop stronger aircraft joints.
Spangle Gall Wasp
A tiny gall wasp that produces flat, disc-shaped spangle galls on the undersides of oak leaves. It alternates between two distinct gall forms across generations.
Did You Know?
A single oak leaf may carry over a hundred spangle galls, yet the tree suffers minimal harm.
