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.
The commonest goldenrod gall is a round gall in the middle of a stem called a ball gall, made by the Goldenrod Gall Fly, Eurosta solidaginis. In spring, the female fly lays her eggs on goldenrod stems. When the larvae hatch, they chew their way into the stems and galls start to develop. very different type of gall is made by a tiny fly called the Goldenrod Gall Midge, Rhopalomyia solidaginis. The gall is a tight cluster of small leaves at the top of a stalk that resembles a green flower and is called a bunch gall, rosette gall or flower gall.
