Eurosta
goldenrod gall flies
Eurosta is a genus of seven North American gall-forming flies in the family Tephritidae. All species induce galls on goldenrod (Solidago) stems. The best-studied species, Eurosta solidaginis, creates spherical stem galls and has served as a model organism for research on freeze tolerance, host-race formation, and plant-insect coevolution. Research has demonstrated that Eurosta galls accumulate environmental contaminants at higher concentrations than surrounding plant tissues, suggesting potential use as pollution biosensors.
