It is native to Europe and Armenia, but is an adventive species in the Nearctic ecozone, where it is found throughout the United States and southern Canada. It has also been recorded from New Zealand, Chile and Argentina. The habitat consists of grassy areas and waste ground. The wingspan is 10–12 millimetres (0.39–0.47 in). The adults have a bronzy or greenish metallic sheen with no markings.The blackish antennae are white ringed to the apex and the basal 2/5 is thickened with projecting scales. They fly during the day as well as after dark. They are on wing in June and July in western Europe and from May to August in North America. The larvae feed within the flowers of Trifolium repens where they feed on the seeds. A larval case is built in the later stages.
