The moth that lives on vegetables (lakhana meaning 'greens') consumes the roots of vegetables (oleraceus). This moth was named with a typo - lacanobia should read as lachanobia but it was never corrected. The fact that its common name, Bright-line Brown-eye should be similar to Brown-line Bright-eye (Mythimna conigera) just adds to the confusion.
Specimens from York Museums Trust Allis Collection
Trying to identify it in the drawers from the Allis/Heron collection, a further complication can be seen - Diataraxia oleracea was the moth's original Linnean binomial.

Here, just for completion's sake, is the illustration from 1843. Not a new species but one that hasn't appeared in the blog before.
