Plain Needle-miner

(Svensson, 1966)445 / 16.024
=Grey Pine Ermine*

Norfolk status
Double or triple-brooded.
Males have pale grey forewings, females are white.

Can be confused with the similar pine feeding species Ocnerostoma piniariella. O. friesei initially has an earlier flight time. Differences in antennae can also aid identification, Ocnerostoma friesei: grey. O. piniariella: ringed white and pale grey (male) and white (female)

The larvae, not distinguishable from O. piniariella, mine the needles of the foodplant from December to March, June to July and sometimes September.
