The goldenrod ball gall fly, Eurosta solidaginis (Diptera: Tephritidae), is parasitized by two eurytomid wasps and preyed on by a mordellid beetle, and two bird species. The birds are known to prey most intensively near a forest edge. The proportion of fly larva parasitized and preyed on by insects was examined, and a decline in the proportional abundance of beetle larvae near the forest was noted. The possible role of birds as the selective force for this distribution is considered.
