Brown-line Bright-eye (left) and Crescent (right) are both primarily coastal. Brown-line Bright-eye is associated with dry grasslands, whereas Crescent is a wetland species. My Brechfa record from Saturday night is likely to be a wanderer from the Tywi or Teifi.
Double Kidney (left) and Lesser Cream Wave (right) are always 'good' species to see, as they usually turn up only once or twice a year at most sites. Both are more widespread in the county than I would have anticipated.
Phycita roborella (left) is surprisingly uncommon in the county, and Chris' record is the first I'm aware of from the Carms side of the Teifi valley; I had it new to Brechfa this summer too. Small Elephant Hawk-moth is surprisingly widely scattered, but does seem to be resident in the Brechfa/Llanllwni area and on Mynydd Du. Isabel's record is new for SN74.
