A Moth Bonanza

After keeping the lights switched off on the moth trap for the past few nights, which was due to the cool, wet and windy conditions, last night I switched them back on as the weather had improved immensely. The wind last night was a light southerly, it was dry and the temperature was up a few degrees.

And didn't the moths know it. Granted a moth bonanza is normally found in July and August when its possible to trap 70+ species, but when the moth numbers have been so low for the past 5 weeks or so, it was good to see 49 moths of 18 species in the trap this morning. For me that was a bonanza!!!

Best of the bunch were one definite and possibly two new moths for my Port & Wey moth list. One of them I'm finding difficult to ID. However I know the other one which was a Pale Prominent Pterostoma palpina. In addition to the new moth/s, I also had 4 first for the year moths, which now brings my garden total to 58.
