Cluster Flies?

Answer

The cluster flies are the genus Pollenia in the blowfly family Calliphoridae. Unlike more familiar blowflies, they do not present a health hazard because they do not lay eggs in human food. They are strictly parasitic on earthworms. However, the flies are a nuisance because when the adults emerge in the late summer or autumn they enter houses to hibernate, often in large numbers and are difficult to eradicate because they favor inaccessible spaces such as roof and wall cavities.
