I was lucky enough to catch a Butterbur at 125w MV last night (16 August) at one of my private sites at Huntingfield. I discovered this morning that the food plant is present nearby.
There has been some searching for this moth in Suffolk in recent years; although in my experience unsuccessfully. I have taken the moth on two previous occasions (at Rendham in 2003 and at Bawdsey in 2013). It seems to turn up when one least expects it!
Despite the blustery conditions overnight I also trapped a high number (16) Square-spotted Clay across my survey area.
Tony and myself tried the good patch of Butterbur at the Newbourne Springs SWT reserve last night without success, using an actinic trap in amongst the foodplant as well as searching by torchlight. The 125w mv trap I also brought along had to be switched off at the start as the outer case of the bulb blew up!
Wine ropes also deployed but not many moths came in to those but nice to see 1 Old lady on them, with another netted in flight just after dusk. Best moth seen probably Epermenia falciformis.
