In July 2019, at the University of Massachusetts Amherst, Dr. Brewer discovered what appears to be Stigmella multispicata in an American Elm (Ulmus americanus). S. multispicata has only been observed in the leaves of the Siberian Elm (Ulmus pumila)(Nieukerkin et al. 2018). We will identify the presence of S. multispicata in the Ulmus genus, with the exception of U. pumila. We will randomly select Elm trees on the University of Massachusetts Amherst campus based on their location. Infested leaves will be collected for study and comparison. S. multispicata was first identified in 2014. There is a need for information on how S. multispicata will affect the Ulmus genus. Further research is required.
