Diamond-back Moth Migration

We are currently on the receiving end of a large-scale migration of Diamond-back Moths (Plutella xylostella) into the UK.  I thought I was doing well with a count of 16 caught at dusk in my Cheltenham garden on 2 June, but have just heard from a recorder in the Stroud area who gave up counting at 100 in his moth trap.  The migration has been mentioned on Springwatch and there is a short video clip of one observer’s experience in Norfolk here:

It would be interesting to record the full scale of the migration in the county, both numbers and locations, so please send in any records.  The web page noted above has a good range of ID photographs; in essence the Diamond-back Moth is small (about 15 mm wingspan), pale in colour and probably in a garden or field near you!
