Flea occurs only 1Sa 24:14; 1Sa 26:20, where David thus addresses his persecutor Saul at the cave of Adullam: ’After whom is the king of Israel come out? after whom dost thou pursue?—after a flea;’ ’The king of Israel is come out to seek a flea!’ In both these passages the Hebrew means to pursue after, to seek one or a single flea. David’s allusion to the flea displays great address. It is an appeal founded upon the immense disparity between Saul as the king of Israel, and himself as the poor contemptible object of the monarch’s laborious pursuit. Hunting a flea is a comparison, in other ancient writings, for much labor expended to secure a worthless result.
Although this insect has been used as a popular emblem for insignificance, yet, when considered by itself, it has high claims upon the attention of the naturalist. Even to the naked eye there is something pleasing in its appearance, and elegant in its postures; but it is indebted to the microscope for our acquaintance with the flexible, highly polished, and ever clean suit of armor in which it is encased cap-a-pie, its finely-arched neck, large beautiful eye, antennae, muscular jointed legs, its piercer and sucker—forming one most complicated instrument—the two long, hooked, sharp claws, in which its legs severally terminate. The agility of the flea places it at the head of all the leaping insects, when its strength is considered in relation to its size, it being able to leap, unaided by wings, 200 times its own length. Owing to the habits of the lower orders, fleas abound so profusely in Syria, especially during the spring, in the streets and dusty bazaars, that persons of condition always change their long dresses upon returning home. There is a popular saying in Palestine that ’the king of the fleas keeps his court at Tiberias;’ though many other places in that region might dispute the distinction with that town (Kitto’s Physical History of Palestine, p. 421).

See INSECTS:
Linnaeus recognized two species of flea, Pulex irritans, the common parasite of man, and Pulex (Sarcopsylla) penetrans, the tropical and sub-tropical jigger flea. More than a hundred species are now listed, and the recent discovery that certain fleas are instrumental in the transmission of the plague has given a new impetus to the study of these tiny pests. A flea that is often commoner in houses than Pulex irritans is the “dog and cat flea,” variously known as Pulex serraticeps, Pulex canis, Pulex felis or Ctenocephalus canis.
Flea. Fleas flourished in the sand and dust of the Holy Land. Classified as parasites, these tiny insects attach themselves to a body and suck blood from their host. Fleas have no wings, but they do have strong legs and can jump several inches at one leap. The flea that lives on man is tiny, but it can be very irritating. David described himself as a mere flea being pursued by a king (1Sa 24:14; 1Sa 26:20). He may have seemed insignificant, but he irritated King Saul.
A flea is a small insect without wings. It has strong legs that help it jump. The Bible mentions the flea only in 1 Samuel 24:14 and 26:20, where David compares himself to a flea.
Many flea species, notably Pulex irritans, are present in Palestine. Globally, there are about a thousand species. These insects survive by drinking the blood of animals and humans. Their bodies are wedge-shaped. This allows them to hide in skin folds on both animals and humans.
Females lay eggs in dusty corners. These hatch into larvae that transform into cocoons. Soon, adult fleas emerge and seek a host. Females need blood to develop eggs.
Flea bites are painful, causing swelling and itching. They are drawn to warmth. In ideal conditions, fleas can live a year without food. However, they feed often. The most dangerous are rat fleas, which spread bubonic plague. There were 41 recorded plague epidemics before the time of Jesus.

Description:
The Common Flea Pulex irritans is one of the fleas that are parasitic on man, but there are other subspecies that also live on dogs, camels, and other mammals. Fleas are very small (about 1.25 millimeters [0.05 inch] long) black jumping insects that suck blood in their adult phase, inflicting itching bites as they do so. Scratching the bites can easily cause infection. Their hind legs are adapted for jumping, and the required tension before a jump is produced by a special sticky protein. The flea strains its leg against the adhesive, and when it snaps free the legs release a surprising amount of energy. A flea less than a millimeter in length can jump well over a meter, that is, more than a thousand times its own length.
Fleas are a troublesome pest, breeding in dirt and dust. The people of biblical times had no defense against fleas, and in houses with mud floors the problem was acute. If fleas got too bad, there was no choice but to move to another house.
Another species of flea (Xonopsylla cheopis) infests the black rat and is the carrier of bubonic plague. See 2.27 Mouse, rat.
Special significance or symbolism:
The flea was a symbol for an insignificant troublemaker, a nuisance who was of no great importance.
Translation:
The translation of 1SA 24:14 should indicate that David is talking in a derogatory way about himself, not about the king. He is referring to himself as “a flea.” In the versions that translate all of David’s words as questions, this is often inadequately conveyed, and the idea is better carried as a question followed by two answers to the question: “What has the king come to find? A dead dog! A flea!” In some languages it may be necessary to say, “I am only a dead dog! I am only a flea!"
There is a difficult textual problem in 1SA 26:14, and scholars are evenly divided about which is the better text. RSV and JB follow the Septuagint and read “my life", while other versions follow the Masoretic Text and read “flea". It is probably best to translate “flea” with a footnote to indicate that instead of “flea” the Septuagint has “my life".
