Flea - Wikipedia. Fleas are insects that form the order. Siphonaptera. They are wingless, with mouthparts adapted for piercing skin and sucking blood, and hind legs adapted for jumping. They can jump a distance some 5. Fleas are external parasites, living by hematophagy off the blood of mammals and birds. Over 2,5. 00 species have been described worldwide. G It, 1962 Some data on ectoparasites of small imammals on. Michael Peter Balzary (born October 16, 1962), better known by his stage name Flea, is an Australian-American musician, best known as a co-founding member and one of.

Want to share IMDb's rating on your own site? The Siphonaptera are most closely related to the snow scorpionflies (Boreidae), placing them within the endopterygote insect order Mecoptera. Fleas arose in the early Cretaceous, most likely as ectoparasites of mammals and marsupials, before moving on to other groups including birds. Each species of flea is more or less a specialist on its host animal species: many species never breed on any other host, though some are less choosy. Some families of fleas are exclusive to a single host group: for example, the Malacopsyllidae are found only on armadillos, the Ischnopsyllidae only on bats, and the Chimaeropsyllidae only on elephant shrews. The cat flea breeds on cats and dogs, and is the vector for Yersinia pestis, the bacterium which causes bubonic plague. Fleas appear in human culture in such diverse forms as flea circuses, poems like John Donne's erotic The Flea, works of music such as by Modest Mussorgsky, and a film by Charlie Chaplin. Diversity. In 2. 00. Medvedev listed 2. The order is divided into four infraorders and eighteen families. Some families are exclusive to a single host group; these include the Malacopsyllidae (armadillos), Ischnopsyllidae (bats) and Chimaeropsyllidae (elephant shrews). Some 6. 00 species (a quarter of the total) are known from a single record from a single host. Over 9. 4% of species are associated with mammalian hosts, and only about 3% of species can be considered to be specific parasites of birds. The fleas on birds are thought to have originated from mammalian fleas; at least sixteen separate groups of fleas switched to avian hosts during the evolutionary history of the Siphonaptera. Occurrences of fleas on reptiles is accidental, and fleas have been known to feed on the hemolymph of ticks. They interestingly do not possess a mandible. If humans had the jumping power of a flea, a 1. Flea legs end in strong claws that are designed to grasp a host. The flea body is covered with hard plates called sclerites. The tough body is able to withstand great pressure, likely an adaptation to survive attempts to eliminate them by scratching. The larvae are small and pale, have bristles covering their worm- like bodies, lack eyes, and have mouth parts adapted to chewing. The larvae feed on various types of organic matter, especially the feces of mature fleas, which contain dried blood. The adult flea's diet consists solely of fresh blood.

This invention relates to a waterproof, airtight and dustproof bag which is used for the extermination of fleas from an animal such as a dog. The bag, which is open. In most species, neither female nor male fleas are fully mature when they first emerge but must feed on blood before they become capable of reproduction. Fecundity varies from around one hundred to several thousand. In some species, the flea lives in the nest or burrow and the eggs are deposited on the substrate. Because of this, areas where the host rests and sleeps become one of the primary habitats of eggs and developing larvae. The eggs take around two days to two weeks to hatch. In laboratory studies, some dietary diversity seems necessary for proper larval development. Blood- only diets allow only 1. Within the cocoon, the larva moults for a final time and undergoes metamorphosis into the adult form. This can take just four days, but may take much longer under adverse conditions, and there follows a variable- length stage during which the pre- emergent adult awaits a suitable opportunity to emerge. Trigger factors for emergence include vibrations (including sound), heat (in warm- blooded hosts), and increased levels of carbon dioxide, all of which stimuli may indicate the presence of a suitable host. These include the right temperature, food supply, and humidity. Generally speaking, an adult flea only lives for 2 or 3 months. Without a host for food a flea's life might be as short as a few days. With ample food supply, the adult flea will often live for up to 1. However, completely developed adult fleas can live for several months without eating, so long as they do not emerge from their puparia. Optimum temperatures for the flea's life cycle are 2. This triggers sexual maturity in the fleas and they start producing eggs. As soon as the baby rabbits are born, the fleas make their way down to them and once on board they start feeding, mating, and laying eggs. After 1. 2 days, the adult fleas make their way back to the mother. They complete this mini- migration every time she gives birth. The Boreidae (snow scorpionflies) are the sister clade to the Siphonaptera. These belonged to three proposed extinct families, the Pseudopulicidae, the Saurophthiridae, and the Tarwiniidae. The last common ancestor of modern Siphonaptera separated from the Mecoptera during the early Cretaceous. Most flea families formed after the end of the Cretaceous (in the Paleogene and onwards). Fleas probably arose in the southern continental area of Gondwana, and migrated rapidly northwards from there. They most likely evolved with mammal and marsupial hosts, only later moving to birds and monotremes. Whiting and colleagues prepared a detailed molecular phylogeny in 2. The Tungidae, including the harmful chigoe flea or jigger, is sister to the rest of the Siphonaptera. Fleas normally specialise in one host species or group of species, but can often feed but not reproduce on other species. Ceratophyllus gallinae affects poultry as well as wild birds. Fleas are not simply a source of annoyance, however. Flea bites cause a slightly raised, swollen itching spot to form; this has a single puncture point at the centre, like a mosquito bite. Fleas can lead to hair loss as a result of frequent scratching and biting by the animal, and can cause anemia in extreme cases. The speaker tries to convince a lady to sleep with him, arguing that if the mingling of their blood in the flea is innocent, then sex would be also. These circuses, extremely popular in Europe from 1. These devices were originally made by watchmakers or jewellers to show off their skill at miniaturization. A ringmaster called a . The infected fleas feed on rodents which then infect the human population with the plague. During World War II, the Japanese army dropped fleas infested with Y. The bubonic and septicaemic plague are the most probable form of the plague that would spread as a result of a bioterrorism attack that used fleas as a vector. He discovered and named the plaguevector flea, Xenopsylla cheopis, also known as the oriental rat flea, in 1. He was followed in this interest by his daughter Miriam Rothschild, who helped to catalogue his enormous collection of the insects in seven volumes.
