I agree the habitus posture is consistent with Plutellidae, but I cannot find any Plutellidae in BOLD with a ragged dark band along the forewing hind margin.
I do nor see here the head structure, colour and upturned palps matching the single specimen from life i;ve seen of S. meloleuca on the ALA, but equally I cannot find a matching Plutella (genus) moth with the same markings as we see here.
I see hair on the top of the head with a central parting, which I interpreted as a possible pair of palps over the head, but perhaps it is hair on head like a Tineid but with a parting. But I don't know any Tineids with a ragged black band along the forewing hind margin.
