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.
Interestingly, the adult goldenrod gall fly does not eat. Goldenrod larvae and gall flies have predators; Downy Woodpeckers and Chickadees know there is a juicy treat waiting for them in those galls and they will break them open to eat a larva. There is a beetle that will burrow into the gall to have a meal.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.
