A flea circus refers to a circus sideshow attraction in which fleas are attached (or appear to be attached) to miniature carts and other items, and encouraged to perform circus acts within a small housing.
The first records of flea performances were from watchmakers who were demonstrating their metalworking skills. Mark Scaliot in 1578 produced a lock and chain which were attached to a flea. Flea performances were first advertised as early as 1833 in England, and were a major carnival attraction until 1930. Some flea circuses persisted in very small venues in the United States as late as the 1960s. The flea circus at Belle Vue Zoological Gardens, Manchester, England, was still operating in 1970. At least one genuine flea circus still performs (at the annual Oktoberfest in Munich, Germany) but most flea circuses are a sideline of magicians and clowns, and use electrical or mechanical effects instead of real fleas.
Techniques with real fleas
Fleas typically live only for a few months and are not trained.
Fleas are observed to see if they have a predisposition for jumping or walking. Once sorted, they are harnessed by carefully wrapping a thin gold wire around the neck of the flea. Once in the harness the fleas usually stay in it for life. The harnesses are attached to the props and the strong legs of the flea allows them to move objects significantly larger than themselves.
Jumping fleas are used for kicking small lightweight balls. They are carefully given a ball; when they try to jump away (which is not possible because of the harness) they shoot the ball instead. Running fleas can pull small carts and vehicles or rotate a Ferris wheel.
There are historical reports of fleas glued to the base of the flea circus enclosure. Miniature musical instruments were then glued to the flea performers and the enclosure was heated. The fleas fought to escape, giving the impression of fleas playing instruments.
Techniques without real fleas
Some flea circuses may appear to use real fleas, but in fact do not. A variety of electrical, magnetic, and mechanical devices have been used to augment exhibits. In some cases these mechanisms are responsible for all of the "acts," with loose fleas in the exhibit maintaining the illusion.
Some "flea circuses" really contain no fleas at all, and the experience and skill of the performer convince the audience of their existence.
