Cluster flies are small, fuzzy flies that often gather in groups. They like to find warm places to rest during the colder months and can sometimes be found buzzing around windows.
生息地: Urban areas
The Cluster Fly has a greyish-olive thorax covered in golden-brown hairs and a darker abdomen with irregular pale patches. It is often larger and more sluggish than a common house fly, and can display an iridescent sheen under certain light.
