Dr. Yuta Karawasaki from Gustavus Adolphus College in Minnesota is conducting research on Goldenrod Gall Flies that create ball galls on goldenrod in our area and is requesting our help in locating potential populations.  While out in the field, please keep your eyes open for stands of goldenrod with numerous ball galls present.  If you find stands of goldenrod with numerous ball galls, please report the location to Bob Honig -  Dr. Karawasaki is only interested in ball galls, so please look for galls that resemble the one in this picture.
