Sorhagenia rhamniella (August Cosmet) - a new genus of moth for me

There are 3 species of Sorhagenia in Norfolk but none of them are common.  Two species have just 3 records each to their name while the third has 13 - from just 4 observers.  So it's no surprise that I hadn't encountered any up to now, but this changed on 15th July when I trapped the commonest of the three, August Cosmet Sorhagenia rhamniella.
