Acentria ephemerella has had some success as a biological control agent of Eurasian watermilfoil (Myriophyllum spicatum) in the Great Lakes region. In Lakes Buckhorn and Scugog, part of the Trent Canal system flowing into Lake Ontario, populations of introduced Eurasian watermilfoil were decimated in the 1980s, likely due to grazing by Acentria ephemerella.

In Cayuga Lake, the introduction of Acentria ephemerella was associated with a decline in Myriophyllum spicatum populations and the recovery of native macrophytes (particularly Elodea canadensis) during the 1990s.

Acentria ephemerella North America, has the potential to be an effective control agent for Eurasian watermilfoil in North America. However, populations in many study sites were lacking the densities of Acentria ephemerella needed to be fully effective.
