Diamondback moth

"Diamondback moth" may also refer to the ermine moth genus Scythropia.

The diamondback moth (Plutella xylostella), sometimes called cabbage moth, is a European moth believed to originate in the Mediterranean region that has since spread worldwide. The moth has a short lifecycle (14 days at 25°C), is highly fecund, and is capable of migrating long distances. It is one of the most important pests of cruciferous crops in the world and usually only feeds on plants that produce glucosinolates. However, not all of these plants are equally useful as hosts to the moth; some discussion of using wintercress as a buffer plant around agricultural fields has occurred, as diamondback moths are highly attracted to that plant but their eggs fail to survive when deposited on it.
