I have had the box out on four occasions for Winter GMS during January - 07th (10C min), 15th (10.4C min), 20th (-2.3C min) and 29th (8.2C min). The minimum temperatures have been quite good for January and the winds have tended to ease back during the nights but I have only had 5 moths (3 x December Moth, Mottled Umber and Chestnut) - and they were all logged on 07th. I have had 3 nights of nothing since then.
I have to say that this is an improvement on 2015-16 when I had 5 nights of nothing during January!
Has anyone else seen anything this year ?
