Smilax leaf spot gall - Meunieriella on-smilax Cedar Rapids/ICNC, Linn County, Iowa, USA July 9, 2011 Size: 5-7mm
In Plant-Feeding Gall Midges of North America, Dr. Gagne reports this type of leaf spot gall on Smilax as undescribed and simply labels it as being made by a "cecidomyiid," so if there is no where to put this, we can frass it.
