Unlike the more familiar blow flies, such as the bluebottle genus Phormia they do not lay eggs in human food.

[13] Cluster flies seek refuge in cold weather and find their way into attic spaces and similar areas indoors.

[14] The typical grass fly Pollenia rudis is about 7 mm long and can be recognised by distinct lines or stripes behind the head, short golden-coloured hairs on the thorax, and irregular light and dark grey areas on the abdomen.

[15] In Popular Culture American rock band, Phish, references the common name of this species on their ninth studio album Farmhouse.

The song, titled Farmhouse, was written by Trey Anastasio and Helena, Montana born bassist and record producer Tony Markellis.
