What are Cluster Flies?

Cluster Flies

Cluster flies, scientifically known as ‘Pollenia rudis’, are a common fly species distinct from other flies like houseflies. They are slightly larger, about 8-10 mm long, with a distinctive golden sheen on their thorax and overlapping wings at rest. Unlike houseflies, they are sluggish in movement and are not associated with unsanitary conditions. Cluster flies breed in the soil, where their larvae parasitize earthworms, unlike houseflies that often breed in decaying organic matter. This difference in breeding habits is crucial for fumigation strategies.
