October Mothing

After an amazing holiday in Ibiza (24 Sep - 1 Oct) when the daily temperatures were between 27.0°C and 29.0°C it was back home to a much cooler Portland.

So just to see what was about, moth-wise, I put the trap out last night and was pleasantly surprised that there were still a few species about, despite the colder nights.

So the numbers, well there were 46 moths of 16 species including 2 firsts for the year and 2 lifers.

  *First for year
