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.
Remember, the goldenrod stems have to have emerged first. Adult gall flies are small (about 5 mm) , clumsy and are poor fliers. (They have difficulty righting themselves if they fall on their backs!) They do most of their traveling by walking.Adult flies only live about 2 weeks, during which time they mate and the females lay their eggs.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.
