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.
In the spring it pupates and by late May or early June emerges from the gall, breaking through the thin surface of its exit hole, as a fly with banded wings. Adults usually live about 2 weeks. A similar gall that is eliptical, not round is produced by the Goldenrod Gall Moth, Gnorimoschema sp.s you walk around Fermilab in the fall keep your eyes open for a round lump on the stems of many of the goldenrod plants that grow throughout the site. This gall is produced by the activity of the Goldenrod Gall Fly, Eurosta solidaginis.
