The Flea (horse)

The Flea was bred by Lord George Bentinck at his Goodwood House stud in Westhampnett. Her sire, Coronation had won the 1841 Derby and Ascot Derby. Coronation stood only a few seasons in the United Kingdom before being exported to Russia. Her dam, Puce (1834 – 1849), was bred by the Duke of Cleveland and was sired by the 1829 St. Leger winner, Rowton.^[2] The Flea's half-sister Monstrosity produced the 1844 2000 Guineas winner The Ugly Buck. Puce's dam, Pucelle, was a daughter of the 1814 Oaks winner Medora and is a tail-female ancestor to St. Marguerite (Thoroughbred family 4-n).^[3] Puce's full sister Virginia produced the multiple stakes winner Virago and is an ancestor of the 1000 Guineas and Oaks winner Thebais.

The majority of the Bentinck Stud, including Puce, was sold in August 1846 to Lord Mostyn.^[4] The Flea was acquired by Frank Clarke (c. 1800 – 1856), who wrote for the racing publication Bell's Life under the pseudonym Pegasus.^[5] The Flea was trained by John Day at Danebury.

The Flea was not raced extensively and only completed as a three-year-old. Ridden by Alfred Day, the son of her trainer, The Flea won the 1000 Guineas by a head from the mares Clarissa and St. Rosalia in a field of 10 runners.^[1] The Oaks winner, Lady Evelyn, did run but was not placed in the race.^[6] The race was later called "unwisely run and unwisely ridden" by the racing press, but Alfred Day's performance was praised.^[7] The Flea's only win was in the 1000 Guineas. She was unplaced for the Ascot Gold Vase in June, the Chesterfield Stakes in July, and the Orange Stakes run at Goodwood in August.^[8][9][10] She was subsequently retired to become a broodmare at the close of the 1849 racing season.
