Explanation of Names
"Sophora Worm" is reference to the native host genus: Sophora.
"Genista Broom Moth" is an odd common name for a native North American moth as Genista (common name of "broom") is an Old World genus, family Fabaceae.
Numerous species of broom have been introduced into North America, some of which have become noxious invasives such as common broom (Cytisus scoparius), French broom (Genista monspessulana) and Spanish broom (Spartium junceum).
