Agrimonia parviflora is a species of perennial herbaceous flowering plant.
Globally, the genus Agrimonia consist of about fifteen species of plants.
Most members of this genus have small yellow flowers with large leaves.
Each leaf can contain up to 17 primary leaflets that are lanceolate in shape with toothed edges.
Because of the aroma and foul taste of the agrimony, predators and parasites such as lice and mites stay away from constantly restocked nest.
[6] Agrimonia parviflora prefers moist and wet grounds and is found in swamps, woodlands, prairies and roadside ditches.
Harvestlice prefers full sunlight and can grow in most soils, including sandy and silty.
Harvestlice is distributed along the Atlantic coast from Georgia to New York but is infrequent in the coastal plain.
