Recent Status: A very common, sometimes abundant immigrant, that can become an agricultural and garden pest in some years.

Life Style: The species can be found all year round as an immigrant. Larvae can survive the winter in mild locations/years. They feed on any member of the Brassicaceae family. They feed underneath leaves with a slight web. There can be many on a leaf of larger plants such as commercially grown brassicas.

Identification: The species can be very variable in pattern and colour, sometimes not showing any sign of patterning and at other times with markings in addition to the three pale dorsal marks that give rise to the ‘Diamond Back Moth’ name when seen from above.
