Goldenrod Gall Fly Life-Cycle. The goldenrod gall fly (Eurosta solidaginis) is a common and widely distributed insect found coast to coast in the central part of North America. The adult flies emerge from their galls in late spring.In Manitoba they emerge mid to late May, or even early June.n southern Manitoba there is one critter that is particularly suited for a class room demonstration of survival at sub-zero temperatures. The larva of the Goldenrod Gall Fly (Eurosta solidaginis) is both common and easy to get.
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.
