Louse (pl.: lice) is the common name for any member of the clade Phthiraptera, which contains nearly 5,000 species of wingless parasitic insects. Phthiraptera has variously been recognized as an order, infraorder, or a parvorder, as a result of developments in phylogenetic research. [1] [2] [3]
The head louse (Pediculus humanus capitis) is an obligate ectoparasite of humans. [1] Head lice are wingless insects that spend their entire lives on the human scalp and feed exclusively on human blood. [1] Humans are the only known hosts of this specific parasite, while chimpanzees and bonobos host a closely related species, Pediculus schaeffi.
Additionally, pill bugs have a thorax consisting of 7 body segments, 5 abdominal segments, and a pleotelson, while Glomeris millipedes lack a visually defined thorax and have 12 body segments total. While the uropods of pillbugs are relatively quite small, flipping a pill bug over will reveal the small uropod overlapping the pleotelson. [ 41 ]
The wingless species can be easily mistaken for bed bugs or lice. While this field hasn’t been fully studied yet, research shows that booklice can also cause allergies. 7. Gnats.
Hippoboscidae, the louse flies or keds, are obligate parasites of mammals and birds. In this family , the winged species can fly at least reasonably well, though others with vestigial or no wings are flightless and highly apomorphic .
Asellus aquaticus can breed throughout the year, if the temperature is high enough: they do not breed under cold temperatures. Maturity can be reached in few months under warm summer temperatures, but maturation may take as much as two years in permanently cold water bodies (e.g., high-latitude or mountain waters). [3]
Body lice can also transmit pathogens, Frye says, which is particularly a problem for people who have poor hygiene, such as homeless populations. Fly bites Single large horsefly bite on left leg ...
