Description

This species is very similar in appearance to Plutella xylostella and can only be distinguished from that species either by examining the larvae, the pupae or the adult genitalia.[3] The diamond pattern on the forewings of this species is variable and can be blurred or faded.[3]

Distribution

It is endemic to New Zealand and is found throughout the country.[4][3]

Habitat and hosts

P. antiphona inhabit open areas including cultivated places like gardens.[3] Larvae of this species feed on plants in the Brassicaceae family.[3]

Behaviour

The larvae make a web of silk on the lower side of the leaves and produce see through windows in the leaf structure as they feed.[3] They pupate in a cocoon made of silk either on the ground or alternatively on their host plant.[3] Adults are on the wing throughout the year and are both day and night flying.[3] They are attracted to light.[3]

Interaction with humans

Although this species feeds on plants in the Brassicaceae family it is not regarded as a serious pest of agricultural crops.[3]
