Adult Splendidofilaria caperata Hibler, 1964 were found in the tunica media of the pulmonary arteries of 21% of 341 crows (Corvus brachyrhynchos brachyrhynchos Brehm) wintering in southern Ontario, Canada. Microfilariae of S. caperata were not observed in the peripheral blood or in skin snips of infected crows. Microfilariae were rarely found in lung blood and then only in small numbers. Microfilariae were apparently overcome in the wall of the pulmonary artery; chronic inflammation was associated with their presence in arterial tissue. Crows apparently acquire S. caperata from insects that hae fed on birds in which a microfilaraemia does develop.
在加拿大安大略省南部越冬的341只短嘴鸦（Corvus brachyrhynchos brachyrhynchos Brehm）中，21%的个体肺动脉中膜发现有1964年命名的成年卡氏华丽丝虫（Splendidofilaria caperata Hibler）。在受感染乌鸦的外周血或皮肤切片中未观察到卡氏华丽丝虫的微丝蚴。在肺血中很少发现微丝蚴，且数量很少。微丝蚴显然在肺动脉壁内被清除；慢性炎症与它们在动脉组织中的存在有关。乌鸦显然是从吸食过有微丝蚴血症鸟类血液的昆虫那里感染卡氏华丽丝虫的。
