The South African species Klugeana philoxalis has been proposed as being of interest as a possible biocontrol agent for dealing with invasive Oxalis pes-caprae in countries where it is a problem. Like many Noctuids, Klugeana philoxalis has larvae that are nocturnal feeders that hide by day. If suddenly illuminated when feeding in the dark, they drop to the ground.
