Xenopsyllinae

	Xenopsyllinae The Xenopsyllinae form a flea subfamily (or depending on classifications a tribe called Xenopsyllini) in the family Pulicidae The Pulicidae are a flea family in the order Siphonaptera. Currently, this family has 181 species in 27 genera. Of these, 16 are known from North America. Like all 2,500 Siphonaptera, the Pulicidae are ectoparasites. These fleas are wingless, l ....

	Pulicidae The Pulicidae are a flea family in the order Siphonaptera. Currently, this family has 181 species in 27 genera. Of these, 16 are known from North America. Like all 2,500 Siphonaptera, the Pulicidae are ectoparasites. These fleas are wingless, laterally flattened, and great jumpers. They must be able to jump quickly and at great relative heights in order to latch onto their host for feeding and for rapid escape from their host. They make incredible jumps using the protein, resilin. It charges the energy in their body, allowing more forceful and frequent jumps than would be possible relying on only their muscles. This also means that they can to jump frequently without exhausting their muscles. They mainly feed on mammal blood, and many Siphonoptera families, including Pulicidae, transmit disease. Ecology Pulicidae feed on mammalian blood. ''Ctenocephalides felis felis'' is also known as the cat flea, and is an extremely important parasite of domestic cats and dogs. They p ...

picture info	Xenopsylla Cheopis The Oriental rat flea (''Xenopsylla cheopis''), also known as the tropical rat flea or the rat flea, is a parasite of rodents, primarily of the genus ''Rattus'', and is a primary vector for bubonic plague and murine typhus. This occurs when a flea that has fed on an infected rodent bites a human, although this flea can live on any warm blooded mammal. Body structure The Oriental rat flea has no genal or pronotal combs. This characteristic can be used to differentiate the Oriental rat flea from the cat flea, dog flea, and other fleas. The flea's body is about one tenth of an inch long (about ). Its body is constructed to make it easier to jump long distances. The flea's body consists of three regions: head, thorax, and abdomen. The head and the thorax have rows of bristles (called combs), and the abdomen consists of eight visible segments. A flea's mouth has two functions: one for squirting saliva or partly digested blood into the bite, and one for sucking up blood from the hos ...

picture info	Insect Subfamilies Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
