Hi Jason,

Can't find any decent pics of P. haasi to do a comparison, but did find this bit of text on a Google search, '...In July an attempt was made by an amateur entomologist to rediscover the species of miromoth, Plutella haasi, of which the only British record is from Beinn Eighe in 1954. Pupae were hatched out from samples of the moth’s likely larval food plant but these turned out to be from a more common, closely related species.'

Don't know if this is up-to-date but would say that it more than likely makes yours P. xylostella.

Cheers,

Adam
