goldenrod flower galls - Schizomyia racemicola

goldenrod flower galls - Schizomyia racemicola
Readville, Suffolk County, Massachusetts, USA
September 2, 2012
Size: 2.3 mm
Dozens of galls formed among normal flower heads on several inflorescences in a single large patch wrinkled goldenrod. A few more galls seen on another plant in partial shade about 100 ft distant. Because inflorescences do not form until midsummer, presumably the adult flight period cannot occur much earlier.
