Distribution
Imago
To reliably separate Ocnerostoma friesei from Ocnerostoma piniariella, it is usually necessary to refer to dissection of the genitalia, although Ocnerostoma piniariella has whitish or grey antennae with white rings, compared to the present species which has wholly grey antennae.
Forewing male pale grey and white in the female with slightly greyish colour along dorsum.
