Moths: November 2019
The wind dropped but it started cloudy and fairly mild before dropping to 2.4°C before dawn.
The trap yielded ten Yellow Dung flies and two Caddis Flies. There was a Mottled Umber on a nearby window. This follows on from the rarer Scarce Umber found on a window earlier in the week. So I guess it is back to reading the fascinating new Atlas of Larger Moths which thudded onto our doormats this week and dreaming of what will happen next year.
Another mild night at 7.7°C but it was much breezier. There were only five moths but surprisingly not one of them was a macro. There were two E. postvittanas and single Common Plume, Diamondback and Crocidosema plebejana.
This time it was mild during the day and the temperature did not drop below 7.7°C. Eleven moths were caught the best of which was our second record of Sprawler.
There were also two Diamondbacks, singles of Rusty-dot Pearl, Setaceous Hebrew Character, Large Yellow Underwing, Large Wainscot and Red-line Quaker plus three Epiphyas postvittana.
The promise of a south-easterly tempted the trap out of retirement. The start did not feel good as the daytime temperature did not rise above 5°C. However by 2100 it was up to 9.8°C but the breeze increased again and showers set in.
There were no moths in the trap but there was a Large Wainscot on the outside.
Unsuitable conditions continue and it is at times like this that those in the know turn their thoughts to moth genitalia. There are a number of micros, plus some even common macros, which can only reliably be identified by examination of their genitalia. A visitor in July was kind enough to get some checked and found the following new records for the Bay;
Epinotia solandriana, Scrobipalpa nitendella, S. instabilella and S. samadensis. He also added the second records for Pexicopia malvella and Borkhausensia fuscescens.
Conditions have not been suitable for the trap of late but it was set up last night. Despite the temperature dropping to 1.4°C there were five moths of five species. They were Silver Y, Black Rustic, Large Wainscot, Angle Shades, and Red-line Quaker. There was also a Minotaur Beetle.
Despite the threat of rain after midnight, which turned out to be torrential, the calm start for the night meant it was worth trying the trap.
Twenty two moths were caught of 13 species. This included seven Rusty-dot Pearls plus singles of Silver Y, Rush Veneer, Diamondback and Cypress Carpet.
