[8] Pseudolynchia canariensis are species-specific (Columbidae) obligate ectoparasites potentially found in many parts of world where domestic pigeons are kept.

Known from wild or feral hosts in continental Africa, the Mediterranean Sub-region, Afghanistan, India, Bangladesh, Nepal, Thailand, Taiwan, Ryukyu Islands, the Philippines, Malaya, and Indonesia, as well as North America and South America in warmer latitudes.

[9] Pseudolynchia canariensis is the definitive host (sexual reproduction takes place in the insect vector) for the protozoan Haemoproteus columbae or pigeon malaria and transmits this parasite to Columbiformes.

[11] The global distribution of H. columbae described in rock pigeons may provide evidence for the wide range of P. canariensis.

[12] Pigeon flies themselves are commonly infested with hyperparasitic mites such as Myialges anchora.
