Leucopis americana
silver fly
Leucopis americana is a species of silver fly in the family Chamaemyiidae, described by Malloch in 1921. Members of this genus are predatory insects that have been investigated as potential biological control agents for hemlock woolly adelgid (Adelges tsugae). The species is part of a group of Leucopis flies under evaluation for release in eastern North America to control this invasive forest pest.
