Pseudolynchia canariensis are found is most part of the world (mainly subtropical and tropical) where pigeons can be found. Areas include Continental Africa, Mediterranean Sub-region, Afghanistan, India, Bangladesh, Nepal, Thailand, Taiwan, Philippines, Malaysia, Singapore, and Indonesia.

Pseudolynchia canariensis is brown and dorsoventrally flattened. This allows the fly to hide in between the feathers of its hosts to avoid detection. Additionally, it has a hard exoskeleton which makes it more difficult for the birds to crush the flies using their beaks when preening.

Pseudolynchia canariensis has a very unique life cycle. Unlike most flies, Pseudolynchia canariensis “gives birth” to its offspring instead of laying eggs. A single egg will hatch inside the fly’s uterus and feed on the mother’s “milk glands”. When the larva becomes a prepupa, the mother will “give birth” to it. Shortly after leaving the mother’s body, it will harden to form a pupa. Finally, it will undergo complete metamorphosis and emerge as a young adult.
Phoresy is a type of commensalism where one species hitches a ride on another species to ensure its dispersal. Pseudolynchia canariensis has a phoretic association withmite species, such as Myialges spp. and Ornitocheyletia hallae volgin, and amblyceran and ischnoceran lice. This allows the mites and lice to be dispersed throughout a wide range of pigeons. This is especially important for these parasites as the hosts will eventually die, thus the Pseudolynchia canariensis is an escape route for them to travel to another host to propagate and survive to pass on its genes to the next generation.

It does not have a holotype. However, it has a syntype stored at the Muséum National d'Histoire Naturelle in Paris.
