Anthonomus ulmi (DeGeer, 1775)
in early spring the larva lives in a closed bud, eats it completely out, then pupates there. It is a prerequisite that the bud remains closed; if not, the larva dies. It is not clear whether the bud shows signs of galling.
Ulmus “campestris”, laevis.
Anthonomus inversus Bedel, 1884; Anthonomus bituberculatus inversus.
The mistaken and confusing association of the elm-species inversus as a subspecies of the Rosaceae-species bituberculatus has misled Buhr and others after him to associate inversus with hawthorn.
