The goldenrod gall fly lives its entire life on goldenrod plants. This fly is small and grows to be about five millimetres long with females usually being a bit larger.Females have an âegg-laying tubeâ (ovipositor) that extends from their abdomen making them easier to identify.oldenrod gall flies do not seem to have any effects on us. They do not sting or bite and they tend to be focused only on mating and goldenrods; in fact, their activities do not even harm the goldenrod.
Cluster flies are capable of crawling through small openings in the walls of a structure. They hibernate in secluded parts of houses like attics and wall voids. On sunny winter days, the wall voids become warm and the cluster flies try to move toward light. Very often they find themselves in the inhabited parts of the house and the move to the windows. They cluster around the windows and they leave stains on walls and curtains if crushed. The cluster fly life cycle begins when a female lays her eggs in the soil in late summer or early fall.
