This uncertainty applies with more than usual force to today's moths. I m currently trying to find out from the sages on the Upper Thames Moths blog what this very distinctive creature in the two pictures above may be. Very distinctive, but a mystery to me in spite of unusually intensive scanning of the Moth Bible. Update: And UTM has come up trumps, as ever. Nigel Partridge spots it as Galleria mellonella, the Wax Moth - one blooming big micro!
But is this little chap below a Muslin Footman? Again, uncertainty creeps in and as 1 Corinthians, Chapter 14, verse 8 rightly puts it: "If the trumpet gives an uncertain sound, who shall prepare himself for the battle?" After all, he or she may be a Scarce Black Arches. Update: or indeed the micro Udea lutealis - the correct ID brilliantly provided in Comments by Ben the Wise of Essex Moths - very many thanks, Ben, as ever.
Finally, I think we have a rather nice whiteish Dun-bar, befitting the first day of a new month, and then um...well, I think it's one of the many varieties of Common or Lesser Common Rustic. Here's hoping for more clarity on the second day of the month. Thanks for your patience. I hope some friendly expert passes by.
