Species Profile
Perizoma bifaciata, the barred rivulet, is a moth in the family of geometer moths (Geometridae). It was first described by Adrian Hardy Haworth in 1809.
The Barred Rivulet faces significant threats from habitat loss and degradation of its specialized wetland environments. Climate change and human development pressures on riparian and marshy areas where its host plants grow have contributed to population declines across much of its range.
Key Facts
