Human Flea
Once common in human homes, now relatively rare in developed countries. Historically responsible for transmitting bubonic plague. Can jump 33 cm vertically.
Did You Know?
Human fleas were major plague vectors — the Black Death that killed 75-200 million people in the 14th century was largely spread by fleas on rats entering human homes.
Paper Wasp
Builds open-comb nests from chewed wood fiber mixed with saliva, creating paper-like material. Has a complex social hierarchy with facial pattern recognition between individuals.
Did You Know?
Paper wasps can recognize individual faces — they use facial patterns to identify nestmates and establish dominance hierarchies, one of the few insects known to have face recognition.
