These pose no threat to human health because they are strictly parasitic on earthworms. Females lay eggs near worm burrows where the larvae hatch out to feed on worms. Genus Pollenia contains 8 British species of Cluster Fly. They are very distinctive in having long wavy underlying golden hair. The individual species can't reliably be identified from a photo and need careful scrutiny of several characters. During cold weather they sometimes seek refuge in houses and then emerge on warm days forming clusters at windows when trying to escape, hence the name 'Cluster Fly'.
