Last night (10th) I trapped not one but two Grass rivulets here at IGC. This is a new species for the site but I am wondering where they came from as the foodplant (Yellow rattle) isn’t present close by. I know Matthew took one of these moths recently at Bawdsey and I am wondering if anyone else has picked it up?
Checking the Suffolk guide online there are only a few recent records and no real suggestion there are colonies as they were both single moths. It is a moth I’ve seen at many chalk grassland sites across the UK during the day as it is easily disturbed from the sward.
Something to watch out for in your own traps or daytime visits.

I had one at home on 9th Neil. I put it down as an immigrant. There is a wide range of immigrants this year. If it keep going it will be one of the best years.
