At last I'm getting a few moths that are not Orthosiae (quakers and relations). The Diurnea fagella was from last night and the other three species from 31st March:
oak nycteoline (easily mistaken for a micro)
Engrailed (indistinguishable from small engrailed and probably the same species)
Brindled pug (one of the first to appear and quite large for a pug)
Things should start to liven up from now on, especially where warm days are followed by cloudy nights.
