This species spends its entire life cycle with A. apus. The females will create larvae in late summer, and they will become pupae and lie dormant in winter months. The adults will then become mature in spring, where they will feed on the blood of nestlings. This species is ectoparasitic, meaning, the parasites will be passed from adult to child.
