[1] It is found in Japan, Taiwan, Vietnam, Indonesia, India, Sri Lanka,[2] Australia, and New Zealand.

[4] Similar to sympatric moth Plutella xylostella, but can be distinguished by much broader wings and genitalia.

Pupa very similar to above mentioned species, but with a pair of hooked setae and maxilla is always shorter than the mid-leg.

[6] In New Zealand they can be observed in a range of habitats including near the edges or clearing of native forest and in cultivated areas such as domestic gardens.

[5] In New Zealand it has been hypothesised that they are hosted by watercress as adults have been observed swarming over plants in this genus.
