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.
Biting Midge (No-See-Um)
A tiny biting midge that is the primary Old World vector of bluetongue virus and African horse sickness virus. It breeds in moist, organically enriched soil and is crepuscular, biting at dawn and dusk. Its northward spread into Europe has introduced bluetongue to previously unaffected areas.
Did You Know?
Climate change has allowed this midge to expand northward into Europe, bringing bluetongue disease to countries that had never experienced it.
