Common White Wave!

Last night we set two 6W Heath traps amongst the Birch trees on Cors Fochno. The biggest surprise was a Common White Wave, a month later than the previous latest county record. It is not obvious whether this is a second or third generation, but it was very fresh looking. We had our first Feathered Thorn and Mottled Umber of the year. Others were Common Marbled Carpet, Pink-barred Sallow, Red-line quaker, Green-brindled Crescent, Autumnal Moth and some November moth aggs., Spruce Carpet, Large Wainscot, Black Rustic. The micros were White-shouldered House Moth, Epinotia Ramella, and Ypsolopha Parenthesella.

  1. Your Common White Wave is an interesting record. I haven't seen any mentioned on other moth blogs this week either.

    1. The only mention I have found so far of individuals in Oct, is on the Dorset Moths website. Here is what they say:"The national norm is of a double brood in southern England and a single brood in northern Britain. The relatively high numbers between the respective double brood peaks in early-June and mid-August suggest an additional univoltine cycle in July. The very few moths seen in October are likely to represent a partial second brood spawned by the univoltine brood.
