Japananus hyalinus nymphs on elms

On July, 12th I observed two late instar nymphs of Japananus hyalinus on two elms (Ulmus sp., observations of those two bushes/young trees are linked in the hopper observations), making me wonder, if elms are a suitable. In a park with many Acer campestre trees and other Acer species, and could be just a coincidence, of course.
