Cluster Fly

Pollenia rudis

Edmonton

The cluster fly (Pollenia rudis) is a medium-sized grayish fly with golden-yellow hairs on the thorax and a dark, checkered abdomen. Adults are commonly associated with buildings because they seek sheltered spaces to overwinter. The larvae develop in soil and are associated with earthworms. One important note: GBIF currently classifies Pollenia rudis in Polleniidae, although older scientific literature commonly placed the species in Calliphoridae.
