The Treble-bar generally occurs singly or sparingly at mv light but can be fairly common to common in West Sussex on the downs, amongst woodland and on heathland. In East Sussex it is currently known only from Lewes, although recent records suggest the moth is on the cusp of recolonising this vice-county. It is very local and irregular in numbers. Adults are on the wing in two broods throughout May and June and again from late July to early September. Larvae feed on St. John's-wort. (Pratt, 2011)
